Helper T cells are capable of influencing a variety of immune cells, and the T cell response generated (including the extracellular signals such as cytokines) can be essential for a successful outcome from infection. In order to be effective, helper T cells must determine which cytokines will allow the immune system to be most useful or beneficial for the host. Understanding exactly ho… WebThe number and function of T cell subsets were reported to be abnormal in patients with MM. The CD4:CD8 ratio is inverted, and the Th1:Th2 ratio among CD4 + cells is abnormal (Mills and Cawley, 1983; Ogawara et al., 2005). T cells from MM patients were shown to function aberrantly (Brown et al., 1998; Frassanito et al., 2001).
