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...
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. Regulatory T cells function in an opposite manner: they dampen or turn off the immune response.
1 7 - Once activated, the Helper T cell starts to divide and produce special proteins to signal other immune cells. 2  The activated Helper T cell will in turn activate other T cells to attack the specific antigen 3  (). It also can go on to activate B cells and create an antibody-mediated response. cells are like the police chiefs of white blood cells. T cells are white blood cells called lymphocytes. There are many different types of T cells that all perform different functions, but among the most important are Helper T cells and Killer T cells.
