The role of tissue resident memory CD4 T cells in Salmonella infection: Implications for future vaccines

Claire E Depew et al. Vaccine. .

Abstract

Salmonella infections cause a wide range of intestinal and systemic disease that affects global human health. While some vaccines are available, they do not mitigate the impact of Salmonella on endemic areas. Research using Salmonella mouse models has revealed the important role of CD4 T cells and antibody in the development of protective immunity against Salmonella infection. Recent work points to a critical role for hepatic tissue-resident memory lymphocytes in naturally acquired immunity to systemic infection. Thus, understanding the genesis and function of this Salmonella-specific population is an important objective and is the primary focus of this review. Greater understanding of how these memory lymphocytes contribute to bacterial elimination could suggest new approaches to vaccination against an important human pathogen.

Keywords: CD4 T cells; Subunit vaccines; Systemic Salmonella infection; Tissue resident memory T cells; Vaccines.
