摘要:
A method of eliciting an immune response against an antigen in a vertebrate subject, the method comprising the steps of providing an antigen-adjuvant composition comprising the antigen and a substantially non-toxic adjuvant molecule having biological activity in mucosal tissues, and administering said antigen-adjuvant composition to the vertebrate subject in a manner such that initial contact occurs in mucosal tissue of the vertebrate subject, whereby an immune response is elicited. Cytokines are preferred adjuvants. Preferred cytokines are interleukin-1α (IL-1α) and interleukin-1β (IL-1β).
摘要:
The present invention relates to immunogenic preparations of peptides comprising amino acid sequences corresponding to antigenic determinants of the envelope glycoprotein of HIV, covalently coupled, directly or through a spacer molecule, to carrier molecules suitable for vaccination of mammals.
摘要:
The present invention relates, in general, to CD6 and, in particular, to a CD6 ligand present on the surface of thymic epithelial cells, monocytes, activated T cells and a variety of other cell types. The invention further relates to methods of inhibiting the interaction of CD6 and the CD6 ligand, and to methods of screening compounds for their ability to inhibit that interaction.
摘要:
In certain aspects the invention provides a selection of HIV-1 envelopes suitable for use as immunogens, and methods of using these immunogens to induce neutralizing antibodies. In certain embodiments, the immunogens are designed to trimerize. In other embodiments, the immunogenic compositions and methods comprise at least one agent for transient immune response modulation during vaccination.
