background: numerous evidences indicate that in some hiv-1 positive patients, the humoral and cellular immune responses are induced against hiv-1 proteins and this is inversely related to the progress of infection. objective: the aim of this study was the evaluation of the adenovectors containing hiv genes in induction of immune responses in mice. methods: the hiv-1 genes including gag p24, rev...

Murine immunization with Trypanosoma cruzi KMP11-HSP70 fused genes but not the KMP11 gene alone elicited both an immunoglobulin G2a long-lasting humoral immune response against KMP11 protein and activation of CD8+ cytotoxic T lymphocytes specific for two KMP11 peptides containing A2 motifs. Moreover, protection against the parasite challenge was observed after immunization with the chimeric gene.

Monitoring antibody response to SARS-CoV-2 is critical for assessing the humoral response, especially important considering emergence of multiple variants concern (VOCs).

One of the promising aspects of the immunological research on chemical war gas is to investigate the immunogenicity of some hazardous compounds such as mustard gas. Mustard gas is categorized as a "hapten" based on its physical and chemical properties. Haptenic chemicals which do not possess immunogenicity could be immunogenic experimentally when conjugated with a suitable protein carrier...

Over the past 20 years, natural killer T (NKT) cells have been shown to play an important role in both innate and adaptive immune responses. In this review, the potential role of NKT cells in transplantation will be discussed, particularly their role in rejection and the induction of a state of tolerance.
