Chimeric Antigen Receptor T-cell (CAR-T) therapy has marked a groundbreaking advancement in the fight against cancer, bringing renewed optimism to patients facing previously untreatable forms of the disease. This innovative treatment harnesses the power of the immune system by genetically modifying a patient’s own T cells to target and destroy cancer cells with exceptional precision. Since its clinical debut in the early 2010s, CAR-T therapy has transformed the landscape of oncology, particularly for hematological malignancies, and continues to expand its potential for broader applications. This overview explores the underlying science, clinical uses, challenges, and the promising future of CAR-T cell therapy, highlighting its pivotal role in the evolving field of medicine as of 2025.
What is CAR-T Cell Therapy?
CAR-T cell therapy represents a form of immunotherapy that modifies a patient’s own T cells—key players in the immune system—to identify and eliminate cancer cells. This transformative treatment involves several critical steps:
T-Cell Collection: The patient’s T cells are extracted from the bloodstream using a technique called leukapheresis.
Genetic Modification: In the laboratory, these T cells are genetically engineered to express chimeric antigen receptors (CARs)—artificial proteins designed to recognize specific antigens present on cancer cells.
Expansion: The engineered T cells are then multiplied in the lab, producing hundreds of millions of CAR-T cells.
Infusion: These bioengineered T cells are infused back into the patient, where they seek out and destroy cancer cells that carry the target antigen.
Monitoring: Following the infusion, patients are closely monitored for treatment response and potential side effects. Since CAR-T cells can persist in the body, they provide ongoing immune surveillance against the cancer.
CARs typically consist of an extracellular domain that binds to a cancer-specific antigen (such as CD19 in B-cell cancers), a transmembrane domain, and intracellular signaling domains that activate the T cell upon contact with the antigen. This design enables CAR-T cells to function like precision-guided missiles, homing in on cancer cells while sparing healthy tissue.
Current Applications
As of 2025, CAR-T cell therapy is primarily utilized for the treatment of blood cancers, with six FDA-approved therapies available:
Tisagenlecleucel (Kymriah): Approved for B-cell acute lymphoblastic leukemia (ALL) and certain types of non-Hodgkin lymphomas (NHL).
Axicabtagene ciloleucel (Yescarta): Approved for diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma.
Brexucabtagene autoleucel (Tecartus): Approved for mantle cell lymphoma and adult ALL.
Lisocabtagene maraleucel (Breyanzi): Approved for DLBCL and other B-cell lymphomas.
Idecabtagene vicleucel (Abecma): Targets multiple myeloma by focusing on the B-cell maturation antigen (BCMA).
Ciltacabtagene autoleucel (Carvykti): Also approved for multiple myeloma.
These therapies have demonstrated remarkable success, achieving complete remission rates of 80–90% in some patients with relapsed or refractory B-cell ALL and sustained responses in 40–60% of DLBCL patients. CAR-T therapy has been especially transformative for patients who have exhausted other treatments, such as chemotherapy and stem cell transplantation.
Challenges and Side Effects
Even with its potential, however, CAR-T therapy is fraught with challenges:
1.Toxicity: CAR-T therapy can lead to significant side effects, including:
Cytokine Release Syndrome (CRS): A dangerous surge of cytokines released by expanding T cells, often causing fever, low blood pressure, and organ dysfunction.
Neurotoxicity: Immune effector cell-associated neurotoxicity syndrome (ICANS) can result in confusion, seizures, or brain swelling.
Off-Target, Off-Tumor Effects: CAR-T cells may attack normal cells that express low levels of the target antigen, leading to unintended toxicity.
2. High Cost: Treatment is extremely expensive, ranging from $373,000 to $475,000 per course, not including hospitalization or follow-up care. This financial burden limits accessibility, particularly in resource-limited settings.
3. Manufacturing Complexity: Producing individualized CAR-T cells is time-consuming (taking 2–4 weeks) and requires specialized, high-tech facilities, which presents logistical challenges.
4. Limited Scope: Current CAR-T therapies are mainly effective against blood cancers. Solid tumors, which make up the majority of cancers, are harder to target due to diverse antigens, immunosuppressive tumor environments, and physical barriers.
5. Relapse: Some patients experience relapse because cancer cells lose the targeted antigen (e.g., no longer express CD19) or because CAR-T cells become exhausted.
Advances and Innovations in 2025
New studies are overcoming these challenges, expanding the scope of CAR-T therapy:
Next-Generation CARs: Advanced CAR designs incorporate multiple signaling domains or target two antigens simultaneously to improve effectiveness and prevent relapse. For example, bispecific CARs are engineered to recognize both CD19 and CD22 antigens at the same time, reducing the risk of antigen escape.
Solid Tumor Research: Researchers are working to adapt CAR-T therapy for use against solid tumors such as glioblastoma and pancreatic cancer. Efforts include targeting antigens like HER2 or EGFRvIII and combining CAR-T therapy with checkpoint inhibitors to overcome the immunosuppressive tumor microenvironment and enhance treatment effectiveness.
Off-the-Shelf CAR-T: Allogeneic CAR-T therapies, derived from healthy donors or induced pluripotent stem cells (iPSCs), aim to reduce manufacturing time and costs, thereby increasing patient access. Companies like Allogeneic Therapeutics are leading clinical trials exploring this promising approach.
Improved Safety: Strategies to minimize toxicity include “suicide switches” or “off switches” (such as iCasp9), which can deactivate CAR-T cells if severe side effects occur. Additionally, enhanced CAR designs are being developed to reduce the risks of cytokine release syndrome (CRS) and neurotoxicity.
Combination Therapies: CAR-T therapy is increasingly being combined with other treatments, such as PD-1 inhibitors or chemotherapy, to boost effectiveness—particularly in tackling solid tumors.
Beyond Cancer: Emerging research is exploring the use of CAR-T therapy for conditions beyond cancer, including autoimmune diseases like lupus, where CAR-T cells target harmful B cells, as well as infectious diseases such as HIV.
Future Potential
Broader Indications: Successful application in solid tumors may establish CAR-T therapy as a frontline cancer treatment, potentially replacing many conventional therapies.
Personalized and Accessible: Integration with AI and bioinformatics could streamline CAR-T design, enabling personalized therapies tailored to each patient’s tumor profile while lowering costs.
Global Reach: Improvements in manufacturing and cost reduction strategies may make CAR-T therapies affordable and accessible in low- and middle-income countries, helping to bridge global healthcare disparities.
Conclusion
CAR-T cell therapy represents a paradigm shift in cancer treatment, offering unprecedented hope for patients with relapsed or refractory blood cancers. Its ability to reprogram the immune system to precisely target cancer cells showcases the remarkable power of biotechnology. While challenges such as toxicity, high costs, and limited effectiveness against solid tumors remain, research in 2025 is rapidly overcoming these hurdles. From allogeneic CAR-T therapies and dual-targeting CARs to expanding applications beyond cancer, CAR-T therapy stands poised to revolutionize medicine, turning personalized, curative treatments into a reality for millions.

For over a century, forensic science has relied on fingerprints as a gold standard for identifying individuals. Even after the emergence of DNA profiling, fingerprint analysis remains one of the most trusted and effective methods of personal identification. Fingerprint analysis plays a crucial role in forensic investigations, providing unique biometric evidence in criminal cases. The fundamental fingerprint patterns—loops, whorls, and arches—form the basis for classification and comparison. This critical review explores the historical evolution, scientific foundations, and current methodologies of forensic fingerprint analysis. Drawing from recent literature, the paper examines identification techniques, technological advancements, and the latest research trends. The review highlights the dynamic evolution of forensic science and fingerprint examination as they continue to integrate cutting-edge technologies.
Introduction
Fingerprints are patterns formed by the elevated papillary ridges on the fingertips, which contain rows of pores linked to sweat glands. The core principle of fingerprint identification is that each individual possesses a unique set of ridges and grooves on their fingertips. These ridges, formed during the early months of fetal development, not only remain consistent throughout a person’s lifetime but also tend to persist even after death, outlasting other recognizable features of the body. To date, no two identical fingerprint patterns have ever been documented in any criminal investigation worldwide. Even monozygotic twins exhibit distinct fingerprints. This uniqueness is rooted in human embryology and genetics, beginning in the fetal stage.
In criminal investigations, law enforcement officers typically collect full-digit prints from both hands, storing them for future identification purposes. Forensic fingerprint analysis serves as a cornerstone of modern investigative techniques. Since the late 19th century, fingerprint identification has provided law enforcement with a reliable method of personal identification based on the distinctive ridge patterns found on human fingertips.
This review aims to provide a comprehensive analysis of the current state of forensic fingerprint analysis by:

Literature Review
2.1 Historical Development
Although DNA profiling revolutionized forensic science, it’s important to distinguish its history from that of fingerprint analysis. DNA profiling was first developed by Sir Alec Jeffreys in 1984 at Leicester University in the UK. Jeffreys, a geneticist, initially worked on genetic links for determining paternity and resolving colonization disputes. His groundbreaking method led to the first criminal conviction using DNA evidence: Colin Pitchfork was arrested after raping and murdering two girls, Lynda and Dawn, in 1983 and 1986, respectively. nvestigators collected semen samples, which were analyzed in a forensic laboratory, linking Pitchfork to the crimes. This landmark case marked the beginning of modern DNA forensics.
However, the history of fingerprint analysis predates DNA profiling and remains a fundamental tool in forensic identification. The systematic study of fingerprints began in the late 19th century with several key milestones:
880s: Sir Francis Galton’s pioneering research on fingerprint classification, which established the foundational principles of ridge patterns.
1892: The first criminal conviction based on fingerprint evidence in Argentina, demonstrating its evidentiary value.
Early 1900s: The development of systematic methods for classifying fingerprints, leading to their widespread adoption in law enforcement.
Mid-20th century: The introduction of Automated Fingerprint Identification Systems (AFIS), enabling rapid and efficient comparison of fingerprint data on a large scale.
The 1990s ushered in an era of rapid technological advancements, including improvements in AFIS, image processing, and digitized databases. These innovations significantly enhanced the efficiency and accuracy of fingerprint identification, cementing its role as a cornerstone of forensic science.
Fingerprint Impression Types
Forensic scientists categorize fingerprint impressions into three primary types:
Latent Prints
Invisible to the naked eye and require special development techniques for visualization.
Formed by natural secretions from the skin (such as sweat, oils).
Require advanced forensic processing techniques for recovery and analysis.
Often challenging to analyze due to environmental conditions and surface properties.
Patent Prints
Visible to the naked eye without the need for additional processing.
Created when fingers deposit materials (e.g., blood, ink, paint) onto a surface.
Easier to photograph and document at crime scenes.
Plastic Prints
Three-dimensional impressions left on soft or malleable surfaces such as wax, soap, or clay.
Directly visible and can be cast or photographed for analysis.
Provide clear ridge detail but are less common at crime scenes.
Fingerprint Fundamentals
The pattern of ridges on a person’s fingertips, palms and soles at birth remains unchanged until death. Consequently, a detective can be certain that a criminal’s fingerprints will remain unchanged until death.There basic patterns of fingerprints are loops, whorls and arches that can be found in fingerprints.About 60 to 65 percent of the populations have loop patterns, 30 to 35 percent have whorls, and only about 5 percent have arches.

Automated fingerprint identification technology
While the collection of identifiable postmortem fingerprints from human remains is a crucial part of the forensic identification process, it is essential that these prints be compared with antemortem records to confirm or establish human identity. The rapid identification of postmortem remains relies heavily on one of the most significant technological advancements in fingerprinting history: the Automated Fingerprint Identification System (AFIS).
This computer-based system, known as AFIS, has evolved from its original use for searching criminal ten-print records to its current application in identifying suspects through searches of latent prints against local, state, and national fingerprint databases.
Key factors in using fingerprints for human identification include the cost-effective and timely reporting of results, which is made possible by fingerprint computer technology. Beyond its role in solving crimes, AFIS also plays a critical role in identifying deceased individuals.
In closed-population disaster scenarios—where the identities of victims are generally known—personal information can be gathered from sources such as airline passenger lists and entered into AFIS to retrieve fingerprint records. These records can then be manually compared with recovered postmortem fingerprints, depending on the number of fatalities.
In larger disasters, the rapid manual comparison of antemortem records may be impractical or impossible. As a result, postmortem prints must be electronically searched using AFIS. Postmortem prints are first scanned into AFIS and encoded—meaning that friction ridge minutiae and other unique characteristics are digitized. Criteria such as pattern type and finger position are then selected, followed by the initiation of the fingerprint search.
Searches of postmortem impressions can take only a few minutes, depending on the submitted criteria, and generate a list of potential candidates with the closest match to the submitted print. Although the “I” in AFIS stands for identification, it is important to note that the actual comparison of candidates and any final identification decision—especially in latent print examination—is made by a certified fingerprint examiner, not by the computer itself.
The FBI also has portable IAFIS terminals that can be deployed to disaster scenes worldwide, enabling remote access to the national fingerprint repository for searching and matching recovered postmortem impressions.
In open-population disasters—meaning that the identities of individuals killed in the event are not readily known—recovered postmortem prints should be searched using an automated fingerprint system to aid in identification. This approach is best illustrated by examining the deployment of AFIS and the use of fingerprint identification for mass fatality victims in the aftermath of the 2004 South Asian Tsunami in Thailand. Over five thousand people were killed in that tragic event, highlighting the importance of robust and efficient fingerprint identification systems for managing large-scale disaster victim identification.
Over five thousand people were killed when tsunami waves struck the coast of Thailand on December 26, 2004. Because Thailand is a popular tourist destination, the victims included not only local residents but also many foreign tourists, particularly from Scandinavian countries. The magnitude of the disaster prompted a global request for antemortem identification records from those believed to have perished in the catastrophe.
In response, AFIS was established to assist in the massive identification effort, as no automated fingerprint system previously existed in Thailand. This deployment underscored the crucial role of fingerprint technology in large-scale disaster victim identification.
Fingerprint cards submitted by various government agencies, as well as latent prints developed on items believed to have been handled by the deceased, were entered into AFIS and used as antemortem standards. The use of an automated fingerprint system for victim identification in Thailand faced challenges related to dimensional variations associated with recovered postmortem impressions.
In some cases, the friction ridge skin may expand or shrink, causing the recovered prints to be distorted in size. Examiners must address these variations in order to successfully correlate the postmortem prints with antemortem records in AFIS.
Additionally, the lack of antemortem fingerprint records—especially in developing countries—combined with the difficulty of recovering quality postmortem impressions can significantly limit the effectiveness of fingerprint identification in mass fatality situations.
Critical Challenges
Although DNA fingerprinting is a highly effective and powerful tool for solving complex cases such as murder and rape, it faces a number of challenges in forensic science that can be difficult to resolve and can render the evidence unreliable. These issues have eroded public trust in genetic evidence. As a result, victims may not be clearly identified, leading to confusion and emotional distress for complainants.
Challenges in DNA profiling include sample degradation, mishandling, errors in hybridization and probing, privacy concerns, negligence, inexperienced personnel, database errors, sample intermixing and fragmentation, incorrect data entry, and storage problems. Additional complications include mismatches, the presence of identical twins, and the possibility of DNA evidence being deliberately planted at a crime scene.
Further issues arise from corruption, evidence tampering, and mistakes during sample labeling. DNA can also degrade with prolonged exposure to sunlight, humidity, and heat. Instrumental errors can also compromise results.
A variety of DNA polymerase enzymes are used, such as Bio-X and Taq polymerase, but each enzyme has its own limitations and sensitivities that can affect the reliability of the analysis.
Privacy Issues
One key disadvantage of DNA analysis is its potential to invade individual privacy. Because a person’s DNA reveals a vast amount of information about their physical and genetic traits, it is highly sensitive and must be carefully protected. Information about an individual’s ethnic background and percentage could be misused and lead to discrimination.
Sensitive genetic information, such as predispositions to hereditary diseases or an individual’s race, can also be revealed through DNA analysis. When this information is exposed to others without consent, it constitutes a violation of human rights and personal privacy.
Lack of Expertise
These fields require trained professionals to handle complex cases effectively. However, sometimes expert witnesses are not truly experts in their field. If the evidence cannot be clearly explained to a layperson, such as a judge, and requires extensive technical justifications to be understood, then the outcome may not be favorable. This lack of expertise undermines the reliability of the evidence and can hinder the justice process.
Low Template DNA
When the amount of DNA in a sample is less than 200 picograms, it is referred to as low template DNA. Such samples are more prone to contamination, making their interpretation more challenging. Low template DNA often reaches the courtroom with inadequate capabilities for sound interpretation, raising concerns about the reliability of the evidence.
However, experts are trained to handle and manage these challenges. One way to address this problem is through the use of PCR (polymerase chain reaction) technology, which can amplify tiny amounts of DNA and generate many copies, enabling a complete DNA profile to be obtained.
Touch DNA
The greater the amount of touch DNA evidence submitted, the lower the quality of the resulting interpretation tends to be. Touch DNA can easily contaminate pieces of evidence, complicating the analysis and potentially leading to unreliable conclusions.
Ecological impacts
Environmental factors such as humidity, temperature, bacterial contamination, moisture levels, ultraviolet (UV) radiation, direct sunlight, and dampness have been shown to significantly influence the accuracy and reliability of DNA typing.
Fake DNA marks Sometimes, counterfeit or synthetic DNA can cause problems by leading to incorrect interpretations. These fake DNA samples result in false conclusions and pose a challenge to fully trusting DNA evidence as an absolute truth.
Instrumental troubles
Biological contamination of tools and instruments, especially when they are old or overused, can prevent obtaining reliable results. Additionally, instrument breakage, software and computational errors, mishandling of equipment, and biased PCR reactions that produce stutter artifacts and false peaks all contribute to inaccuracies in DNA analysis.
Non-invasive methods for determining age and health status
Advanced molecular forensic techniques
Improved preservation techniques for degraded prints
Conclusion
Fingerprint identification is the oldest forensic discipline known to humanity. It remains a crucial element in criminal investigations and individual identification. The integration of digital technologies, molecular analysis, and artificial intelligence represents the future of fingerprint forensics, offering unprecedented potential in criminal identification and forensic examination. Identifying remains through fingerprints fulfills one of the most important and challenging objectives in forensic identification: providing timely and accurate information to families about the fate of their loved ones.
Forensic science continues to evolve, delivering advanced and reliable fingerprint analysis methods that expand traditional practices through modern technological advancements. However, the extremely small amounts of DNA found in samples and the pressure to secure convictions can sometimes lead to biased results. Although biological errors are rare, human mishandling remains a significant risk. Poor laboratory practices may cause false outcomes, and there is a possibility that DNA found at a crime scene could be from someone unrelated to the crime.
While forensic DNA typing has made a tremendously positive impact on the criminal justice system, its reliability should never be taken for granted. Each person’s DNA is unique—a “signature” that distinguishes every individual—but carelessness in handling this delicate evidence can compromise its integrity, raising doubts about its trustworthiness.
The treatment of cancer has evolved significantly in recent years, with chemotherapy and immunotherapy emerging as two major approaches in cancer therapy. Chemotherapy has been the cornerstone of cancer treatment for decades, whereas immunotherapy, a novel treatment approach, has gained significant attention for its potential to improve survival rates and reduce side effects.
