1.	Which of the following type of cells recognize and kill the abnormal pathogen infected cells?(a) Mast cells(b) B-lymphocytes(c) T-lymphocytes(d) NeutrophilsThe question was asked in unit test.My doubt stems from Cell Signaling and Signal Transduction in portion Cell Signaling and Signal Transduction of Cell Biology
Answer» Right answer is (C) T-lymphocytes Easy explanation: The T-lymphocytes are IMMUNE cells that RECOGNIZE and kill the PATHOGEN infected target cells in an orderly manner (apoptosis). These cells accomplish the feat by binding to the cell surface receptors of infected/ abnormal cell.
