B cell-specific deficiencies in mTOR limit humoral immune responses.
Generation of high-affinity Abs in response to Ags/infectious agents is essential for developing long-lasting immune responses. B cell maturation and Ab responses to Ag stimulation require Ig somatic hypermutation (SHM) and class-switch recombination (CSR) for high-affinity responses. Upon immunization with either the model Ag 4-hydroxy-3-nitrophenylacetyl hapten (NP) conjugated to chicken γ gl...
متن کاملBisphosphonates target B cells to enhance humoral immune responses.
Bisphosphonates are a class of drugs that are widely used to inhibit loss of bone mass in patients. We show here that the administration of clinically relevant doses of bisphosphonates in mice increases antibody responses to live and inactive viruses, proteins, haptens, and existing commercial vaccine formulations. Bisphosphonates exert this adjuvant-like activity in the absence of CD4(+) and γ...
متن کاملAn HIV-1 Mini Vaccine Induced Long-lived Cellular and Humoral Immune Responses
Memory formation is the most important aspect of a vaccine which can guarantee long-lasting immunity and protection. The main aim of the present study was to evaluate the memory immune responses after immunization with a mini vaccine. Mice were immunized with human immunodeficiency virus-1 P24-Nef fusion peptide and then cellular and humoral immune responses were evaluated. In order to determin...
متن کاملGuidance of B cells by the orphan G protein-coupled receptor EBI2 shapes humoral immune responses.
Humoral immunity depends on both rapid and long-term antibody production against invading pathogens. This is achieved by the generation of spatially distinct extrafollicular plasmablast and follicular germinal center (GC) B cell populations, but the signals that guide responding B cells to these alternative compartments have not been fully elucidated. Here, we show that expression of the orphan...
متن کاملMitogenic Activation of B Cells Results in Specific Immune Responses
We have suggested before that thymus-independent immune responses to certain antigens are caused by special properties of the antigens concerned, namely that they are B-cell mitogens (1). Actually all thymus-independent antigens (TI) 1 we have tested so far were found to be competent to activate DNA and polyclonal antibody synthesis in nonprimed B cells cultured in vitro (2). Since the TI antig...
