Role of T Follicular Helper cells in Multiple Sclerosis.

Abstract

Multiple Sclerosis (MS) is a chronic, inflammatory and neurodegenerative disease which results from the destruction of myelin and associated collateral tissue damage within the central nervous system (CNS). MS is a highly diverse disease with different clinical profiles. During the past decade, several new treatment options have been introduced, but no treatment completely stops the disease progression. Therefore deeper understanding of the disease mechanism is necessary to develop novel therapeutic strategies. While yet to be proven, there is evidence suggesting the involvement of T follicular helper (Tfh) cells, a CD4 T cell subset specialized for the provision of help to B cells, in the pathogenesis of MS. In this review, I will discuss the potential pathogenic roles of Tfh cells in the course of MS.
