Monoclonal antibodies (MAbs) have been used to treat human disease for over 20 years, and have found a range of applications, predominantly in inflammatory and neoplastic disorders. They are attractive therapies due to their unique specificity and capacity for production on an industrial scale. Cytotoxic MAbs, those that trigger lysis of their cellular target, were first used to probe experimental allergic encephalomyelitis, the standard animal model of MS. Since then, antibodies with specificity for a variety of lymphocytic antigens have been used in MS, with variable results. On the basis of experience with the anti-CD52 antibody, alemtuzumab (Campath-1H), it has been postulated that clinical efficacy of some MAbs in MS may not result from cellular depletion, but from the immunomodulatory effect of the subsequent immune system reconstitution.

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
Hybridoma Technology01:31

Hybridoma Technology

Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
