Rhombus - Area. 1  As for all parallelograms, the area K of a rhombus is the product of its base and its height (h). 2  The area can also be expressed as the base squared times the sine of any angle... 3  or in terms of the height and a vertex angle... 4  or as half the product of the diagonals p, q...
Three broad categories of T cells. 1  Helper T cells augment the immune response by recognizing the presence of a foreign antigen and then stimulating antibody production and producing cytokines that âturn onâ or activate other T cells. 2  Regulatory T cells function in an opposite manner: they dampen or turn off the immune response.
In this chapter we will discuss the two responses in detail and we will start with the first one. The cell mediated immune response The cell mediated immune response can be divided into two phases; â¢ The activation of naive CD4+ and CD8+T cells and their differentiation into effector T cells. â¢ The effector phase whereby the effector CD4+ and CD8+ T cells eliminate infection.
