Biological response modifiers (BRMs) are substances that modify immune responses. They can be endogenous (produced naturally within the body) or exogenous (as pharmaceutical drugs ), and they can either enhance an immune response or suppress it .
Immunosuppressive drugs, also known as immunosuppressive agents, immunosuppressants and antirejection medications, are drugs that inhibit or prevent the activity of the immune system. Classification [ edit ]
Active immunotherapy is a type of immunotherapy that aims to stimulate the host's immune system or a specific immune response to a disease or pathogen and is most commonly used in cancer treatments. [ 1 ] [ 2 ] Active immunotherapy is also used for treatment of neurodegenerative disorders , such as Alzheimer's disease , Parkinson's disease ...
This list of over 500 monoclonal antibodies includes approved and investigational drugs as well as drugs that have been withdrawn from market; consequently, the column Use does not necessarily indicate clinical usage. See the list of FDA-approved therapeutic monoclonal antibodies in the monoclonal antibody therapy page.
Immune responses depend on lymphocyte proliferation. Lymphocyte proliferation is the multiplication of lymphocyte cells used to fight and remember foreign invaders. [60] Cytostatic drugs are a type of immunosuppressive drug that aids in slowing down the growth of rapidly dividing cells.
Immunosuppressive drugs have the potential to cause immunodeficiency, which can increase susceptibility to opportunistic infection and decrease cancer immunosurveillance. [9] Immunosuppressants may be prescribed when a normal immune response is undesirable, such as in autoimmune diseases. [10]
However, strictly speaking, immunogenicity refers to the ability of an antigen to induce an adaptive immune response. Thus an antigen might bind specifically to a T or B cell receptor, but not induce an adaptive immune response. If the antigen does induce a response, it is an 'immunogenic antigen', which is referred to as an immunogen.
There are two main categories of immunostimulants: [1] Specific immunostimulants provide antigenic specificity in immune response, such as vaccines or any antigen.; Non-specific immunostimulants act irrespective of antigenic specificity to augment immune response of other antigen or stimulate components of the immune system without antigenic specificity, such as adjuvants and non-specific ...
