چکیده

The murine model of leishmaniosis is a prototypic example for the critical role played by T helper cells in immunity to pathogens. Cytokines, such as interleukin-12 and interleukin-4, are the major regulatory factors for differentiation of naive T helper cells into T helper 1 and T helper 2 cells, respectively. T helper 1 cells, which are cellular immune mechanisms involving gamma interferon production, are associated with protection against murine leishmaniosis. Loss of T helper 1 activity (i.e., reduced gamma interferon production and lack of macrophage activation) leads to a fatal progressive course of murine leishmaniosis. Knowledge of the murine model of leishmaniosis is now contributing to studies of infectious diseases in humans, livestock and companion animals. Greater insight into the pathogenesis, diagnosis and therapy of infectious diseases will be gained from the analysis of cytokine-dependent regulation of T helper responses during infection. In particular, the development of prophylactic and therapeutic vaccines will benefit significantly from these studies.

The role of T helper 9(Th9) against Infectious Diseases

Background and aims: Infectious diseases are disorders caused by organisms such as bacteria, viruses, fungi or parasites .The Th9 subset develops in response to combined signals from TGF-b and IL-4 among a cacophony of other cytokines in an extracellular milieu. T helper 9 (Th9) cells,  as a novel CD4 T cell subset, seem to play a complex role in the outcome of specific immune responses. In thi...

Effect of pleurotus sajor-caju polysaccharide encapsulated in poly D, L lactide-co-glycolide nanoparticles for HPV vaccine in murine model

Objective(s): In the current work, poly D, L lactide-co-glycolide (PLGA) particles were applied for a viral vaccine for the delivery of antigens in cytosolic pathway by increasing the antigen presentation to T-lymphocytes. HPV-E7 protein with PLGA particles has been reported as a potent adjuvant for HPV vaccine by encapsulating protein into the PLGA particles. Polysaccharide from Pleurotus sajo...
