Abstract:
Natural killer (NK) lymphocytes represent the first line of defense against virally infected cells and tumor cells. The role of NK cells in immune responses has been markedly explored, mainly due to the identification of NK cell receptors and their ligands, but also through the analysis of mechanisms underlying the effects of various cytokines on NK cell development and function. A population of lymphocytes that shares function and receptors with NK cells is represented by natural killer T (NKT) cells. NKT lymphocytes are regulators of both innate and adaptive immune responses, but have also been reported to function as effector antitumor cells. The marked progress in our understanding of the biology, development, and function of NK/NKT cells has provided the basis for their potential application in tumor clinical trials.

Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...
