Neutrophils immune system function

In contrast to adaptive immune function, fewer studies have examined effects of TCDD on the innate immune system. Furthermore, of the limited data available, much of it is inconsistent. For example, natural killer (NK) cell activity has been reported to be unaffected,80,93 diminished,94 and increased95 following exposure to TCDD. Although a thorough assessment of AhR expression in all innate cell lineages has not been conducted, neutrophils and macrophages express the AhR,8,96 and neutrophils are affected...

The circulatory system contains a number of types of cells. Nearly half of the volume of whole blood consists of red blood cells whereas only about / of the blood consists of white blood cells. The function of the red blood cells is to transport ojtygeri to the tissues. White blood cells are part of the immune system. There are several types of white blood ceils neutrophils, macrophages, and lymphocytes. Neutrophils are also called polymorphonuclear leukocytes. The smallest type of ceil in the bloodstream is the platelet. Platelets are used in the clotting of blood, as outlined under Vitamin K. 

The basis for the effector function by antigen-specific lymphocytes - especially antibody-secreting B cells, Td cells, and Tc cells - and the participation of other cellular components of the immune system in acquired immunity - including NK cells, macrophages, and neutrophils - have already been emphasized in other sections of this volume. It has also been emphasized that Th cells play an important effector role in acquired immunity as regulators in the growth and differentiation of B cells and Tc cells. In this regard, it is important to note that both populations of T cells whose participation in an acquired immune response is mediated by the secretion of lymph-okines, that is, Th and Tq cells, are characterized by the expression of CD4.
