Cellular Immunology concerns with the interactions between cells and molecules of the immune system, and how such interactions contribute to the recognition and elimination of infectious agents. Vertebrates possess a range of nonspecific mechanical and biochemical defenses against routinely encountered microorganisms. Key processes in immune reaction are antigen recognition, co-stimulation, memory cells activation and elimination of the antigens. Immunotherapeutics are the medicines that are used in the treatment of disease by inducing, enhancing, or suppressing an immune response. Cellular Immunology-2017 is the best platform for the eminent scientists, delegates, young researchers to update the new developments and breakthroughs in the field of Cellular Immunology and Immunotherapeutics.
