TH cells play a central role in the immune response. These cells are specially prolific cytokine producers. Once activated by an antigen, they can use these chemical messengers to induce the formation of TC cells, activate macrophages and formation of many antibodies by B-cells. Functions of TH cell are as follows in the next page (Fig. 10.4): 1. An APC [...]

In this article we will discuss about the two parts of cell division: 1. Mitosis 2. Meiosis. The process in which a cell divides to form two new cells, each containing a nucleus, is called cell division. It is of two types i.e., mitosis and meiosis. In mitosis, which is also called vegetative cell division, the chromosomes in the nucleus [...]
