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 ...
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 .
Pemivibart, sold under the brand name Pemgarda, is a monoclonal antibody medication authorized for the pre-exposure prophylaxis (prevention) of COVID‑19. [4] Pemivibart was developed by Invivyd. [3] [5] The US Food and Drug Administration (FDA) issued an emergency use authorization for pemivibart in March 2024. [4] [5]
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 ...
The advantage of active monoclonal antibody therapy is the fact that the immune system will produce antibodies long-term, with only a short-term drug administration to induce this response. However, the immune response to certain antigens may be inadequate, especially in the elderly.
Biologic response modifiers act by altering the immune response of the human body. The mechanism of action is either through interfering with the effect of cytokines, inhibiting the costimulation of T cell activation, or inhibiting B cells. [15] Cytokines are proinflammatory and are responsible for regulating the human immune response. [17]
A lower incidence of hypothyroidism was observed in a trial of combined B cell depletion and immune checkpoint inhibitor treatment compared with studies of immune checkpoint inhibitor monotherapy. [29] This holds promise for combining check point inhibitor therapy with immunosuppressive drugs to achieve anti-cancer effects with less toxicity.
The mechanisms of absence of immune response may vary and involve complex immunological interactions, but can include absent or insufficient co-stimulatory signals from antigen-presenting cells. Haptens have been used to study allergic contact dermatitis (ACD) and the mechanisms of inflammatory bowel disease (IBD) to induce autoimmune-like ...
