Transcriptional and migration regulation of T follicular helper cell differentiation

Abstract

T follicular helper cells (TFH) are specialised CD4+ T cells that promote B cells maturation into antibody secreting plasma and memory cells. Most of the current vaccines generate protection via the induction of long-term antibody responses and circulating TFH are reliable predictors of vaccine response. Conversely, dysfunctional TFH cells are associated with the pathogenesis of immunodeficiency, systemic autoimmunity and allergy. Despite their importance, we have an incomplete understanding of how TFH cells differentiate and function in distinct inflammatory settings. Answering this question has broad health implications to stimulate rational development of vaccines and therapeutics against..
