HLA-KIR Interactions and Immunity to Viral Infections

Host genetic factors play a central role in determining the clinical phenotype of human diseases. Association between two polymorphic loci in human genome, human leukocyte antigen (HLA) and killer cell immunoglobulin-like receptors (KIRs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. Hence, defining the influence of genetic di...

Staphylococcal Enterotoxin B (SEB) Induces Memory CD4 T Cell Anergy in vivo and Impairs Recall Immunity to Unrelated Antigens

INTRODUCTION Naïve and memory T cells can utilize unique regulatory pathways to promote protection but prevent self-reactivity. A bacterial superantigen SEB exploits unique TCR proximal signaling processes in memory CD4 T cells to induce clonal anergy. The aim of this study was to determine if SEB could antagonize memory CD4 T cells in vivo and whether there would be consequences on recall immu...

BALB/c Mice Immunity to Hydatidosis Induced by In-vitro Reared Echinococcus granulosus Adult Worm Antigens

Background: Echinococcosis is a zoonotic parasitic disease caused by the larval stage of Echinococcus granulosus. Several native and recombinant antigens, derived from different stages of E. granulosus life cycle, have been used for vaccine trials. In vitro reared adult worms are good candidates for vaccination as they do not produce fertile egg/s and do not have any risk of contamination for r...

Chronic Leishmania donovani infection promotes bystander CD8+-T-cell expansion and heterologous immunity.

It has been proposed that long-lived memory T cells generated by vaccination or infection reside within a memory compartment that has a finite size. Consequently, in a variety of acute infection models interclonal competition has been shown to lead to attrition of preexisting memory CD8+ T cells. Contrary to expectations, therefore, we found that chronic Leishmania donovani infection of Listeri...
