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 ...
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 .
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.
Imiquimod, sold under the brand name Aldara among others, is a medication that acts as an immune response modifier that is used to treat genital warts, superficial basal cell carcinoma, and actinic keratosis. [4] Scientists at 3M's pharmaceuticals division discovered the drug and 3M obtained the first FDA approval in 1997. As of 2015, imiquimod ...
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]
Red-eyed flies lacking antimicrobial peptide genes are susceptible to infection, while white-eyed flies have a wild-type immune response. Antimicrobial peptides are produced by species across the tree of life, including: bacteria (e.g. bacteriocin, and many others) fungi (e.g. peptaibols, plectasin, and many others) cnidaria (e.g. hydramacin ...
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 ...
Inflammatory cytokines play a role in initiating the inflammatory response and to regulate the host defence against pathogens mediating the innate immune response. [4] Some inflammatory cytokines have additional roles such as acting as growth factors. [5] Pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α also trigger pathological pain ...
