Detoxified cobra venom and its constituent neurotoxins have been reported to have potent antiviral activity. Others have reported that snake venoms were generally immune stimulants. Recent research has revealed more specific details on the effects of detoxified venoms and isolated alpha-neurotoxins on cells of the immune system. Exposure of the immune cells to these detoxified proteins yields a strong response in the innate immune reaction that represents the immune systems initial response to infectious agents. Of particular relevance is the marked increase in the expression of genes associated with the production of gamma interferon, a potent antiviral agent and regulator of the immune response. The ability to induce this strong innate response has significant application to those with weakened immune systems where their ability to fight infection has been compromised. It also has the potential application to act as a method to protect individuals from contagious infectious agents as a substitute for anti-viral vaccines.

Provided herein are dual epitope polypeptides and electrophilic analogs thereof having a superantigenic epitope and at least one other epitope effective to induce the production of antibodies with binary specificity for the epitopes on a polypeptide antigen. Also, provided are electrophilic analogs of polyclonal B cell stimulants or lipids, polysaccharides and lipopolysaccharides or nucleotides. In addition, provided herein are methods for increasing production of binary epitope specific antibodies recognizing B cell polypeptide antigens, for stimulating production of antibodies using one or more of the polypeptides or electrophilic analogs and for isolating binary epitope specific antibodies or fragments thereof. Further provided are the antibodies so produced and methods of treating HIV using the same.

The traditional Chinese medicine immune stimulant is low in drug resistance and few in drug residue, does not have a toxic and side effect, and has a good prevention effect in the aspect of preventing an Eimeria tenella disease.

The invention relates to a preparation method of APP (Actinobacillus Pleuropneumoniae) OMVs (Outer Membrane Vesicles) and a vaccine of the APP OMVs, and belongs to the technical field of biology. The preparation method comprises the steps of culturing APP shope strains in vitro by using a culture medium which is in iron ion limit, obtaining acellular cultural supernatant after carrying out centrifugation and 0.22-[mu]m filtration treatment, and preparing the OMVs released by germs through ultracentrifugation, wherein the observation through a transmission electron microscope shows that the diameter of most OMVs is 50 to 100 nm, the OMVs are used as subunit vaccines to carry out secondary intranasal immunization on a mouse, the weight of the OMV immune mouse is increased for a long time, and the visual forms of lungs have no obvious difference from a PBS (Phosphate Buffer Saline) immune group. Meanwhile, an experiment shows that the OMVs are efficient immune stimulants, not only can high-level IgG (Immunoglobulin G) be stimulated to be generated by mouse sera, but also high-level IgA (Immunoglobulin A) can be generated in mouse lungs, mucosal immunity of the mouse lungs is effectively stimulated, and a better application prospect of using the OMVs as the subunit vaccines is expressed.

The invention discloses an immune adjuvant of a foot-and-mouth disease vaccine and application of the immune adjuvant, and belongs to the field of biological vaccines. The immune adjuvant is a 3D protein fragment of foot-and-mouth disease viruses. Experiments prove that after the expressed 3D protein fragment is compatible with antigens, animals are immunized, the immunogenicity of multi-epitope antigens can be enhanced, and high-level protective neutralizing antibodies are produced. In vitro stimulation shows that after the 3D protein fragment of the foot-and-mouth disease viruses is separately adopted or compatible with the multi-epitope antigens, lymphocyte proliferation response can be produced, namely the immune adjuvant can be used for enhancing immune response, distinguishing infection and immunizing the animals and is a good immune stimulant and a vaccine molecular marker.
