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.
Dendritic cell are immune system cells whose function is to identify cancer cells, and pathogens like viruses, bad bacteria and fungus, so the the immune system T cells can then kill them. If a cancer cell is not identified by a dendritic cell, the T cells won't know it needs to be killed.
