LCKstands forLymphocyte Cytotoxicity Killing
Full Form of LCK
What is LCK?
Lymphocyte Cytotoxicity Killing (LCK) refers to the process by which cytotoxic lymphocytes such as T cells and natural killer cells induce apoptosis or lysis of target cells, including virus-infected cells, tumour cells, and foreign cells. This mechanism is central to cellular immunity and involves release of perforin and granzymes, as well as Fas ligand interactions. In India, LCK assays are routinely used in immunology research and clinical diagnostic laboratories to evaluate immune function in conditions like HIV/AIDS, cancers, and autoimmune disorders. The test helps determine the functional capacity of a patient's cytotoxic cells, guiding therapy decisions in bone marrow transplantation and immunotherapy. LCK is also a key topic in medical examinations such as NEET PG, AIIMS, and USMLE, where understanding the molecular steps of cytotoxicity is essential. Given the rising prevalence of immune-mediated diseases and cancer in India, LCK-related studies are gaining prominence in both academic and clinical settings. The acronym is widely referenced in textbooks, research articles, and medical curricula to describe the final effector phase of cell-mediated immunity.

LCK — frequently asked questions
What is the full form of LCK?
The full form of LCK is Lymphocyte Cytotoxicity Killing, which describes the mechanism by which lymphocytes kill target cells in the immune response.
How is LCK used in Indian medical practice?
In India, LCK assays are used in diagnostic labs to evaluate immune function in patients with HIV, autoimmune disorders, and after organ transplants, helping clinicians tailor immunotherapy.
Is LCK important for NEET PG or AIIMS exams?
Yes, LCK is a recurring concept in immunology questions for NEET PG, AIIMS, and other postgraduate medical entrance exams, often tested through mechanisms of T-cell cytotoxicity.
