NK(natural killer)cells
A type of immune cell that has granules (small particles) with enzymes that can kill tumor cells or cells infected with a virus (Human natural killer cell, colorized scanning electron micrograph) NK cells are the type of lymphocytes. they are part of innate immunity amd B-cell and T-cell are the part of adaptive immunity. there are mainly three types of lymphocytes (i)Tcells (80% concentration) (ii)Bcells(5-10% concentration) (iii)NK cells(5-10% concentration) NK is differentiated from B-cells and & T-cells Because they have different receptors. (T-cells have their on receptor like CD4 CD8.) B cells has their on antibodies. NK cells are not having surface markers. their cell surface are normal no protein bind or any type of structure on surface. Bcell and Tcell are involved in processing. B cell are firstly produce antibodies and then attack on antigens. thus,T cells killl antigens by binding on their receptors. but what NK cells do? they naturally k...
