THE DAWNING OF AVIPTADIL
A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.

What's the Difference Between IG [Immuno Globulin] and Vaccine? IG is a substance made up of antibodies that are naturally made by the body to provide protection from certain diseases. A vaccine is a substance made up of actual viruses or bacteria that stimulate the body to make more antibodies.

The addition of VIP was associated with a significant increase in the production of IgA, whereas IgG levels were significantly reduced. Both these effects were restricted to LPMC. LDA showed that the IgA-enhancing effect was associated with an increase in the number of IgA-producing precursor cells and with variation in the regulatory phenomena involved in IgA production.

Further investigation demonstrated increased intracellular cAMP concentration after VIP administration, and showed that the protective effect of VIP on concanavalin A-induced hepatitis was mediated mainly through VIP receptor 1 (VPAC(1)). These results suggest that VIP is capable of attenuating immune-mediated liver injury in vivo. This effect is associated with its downregulation of critical inflammatory mediators and its upregulation of anti-inflammatory cytokine through VPAC(1), possibly via the cAMP-dependent pathway.
