Abstract

Naga Anusha P, Aliya Siddiqui and Hima Bindu A

The hypothesis of immune responses is predicted on theory of immune system that is capable of eliminating foreign antigens including tumor specific antigens in the process, immunosurveillance. To defense against tumors immune system activates cell mediated and humoral immune responses, cell mediated immune system protects the body from itself by controlling cancerous cells, this includes activation of Cytotoxic T Lymphocytes, Natural Killer cells, Macrophages, Dendritic Cells, Lymphokines, etc., where as humoral immune system recognizes foreign particles. These cells play important role in defending as well as in diagnostic processes. Here I discussed about the cell mediated and humoral mediated immuno mechanisms involved in the defense mechanism against tumors.
