Answer #1

Answer:- B) NK cells

Natural killer (NK) cells are lymphocytes has ability to kill tumor cells without deliberate immunization or activation.
on activation, NK cells release cytokines and chemokines that induce inflammatory responses; modulate monocyte, dendritic cells, and granulocyte growth and differentiation; and influence subsequent adaptive immune responses.

Natural killer cell deficiency (NKD) is a primary immunodeficiency in which main defect lies in CD56+CD3 natural killer (NK) cells which mediate cytotoxicity against tumors.

please give a thumbs up if the answer help you. Thank you!

Cancer can be defined as an abnormal proliferation of cells that defy the normal regulatory controls observed by normal cells. Recently, histone deacetylation therapies have been attempted in the treatment of certain cancers [reviewed by Delcuve et al. (2009)]. Specifically, the FDA has approved histone deacetylation (HDAC) inhibitors for the treatment of cutaneous T-cell lymphoma. Why does histone acetylation might be associated with cancer? Low acetylation rates often lead to increased cell proliferation, the major cause of tumor. Normally, acetylation...
