Yang Q, Zhang F, Chen H, Hu Y, Yang N, Yang W, Wang J, Yang Y, Xu R, Xu C. The differentiation courses of the Tfh cells: a new perspective on autoimmune disease pathogenesis and treatment. Biosci Rep 2024; 44:BSR20231723. [PMID: 38051200 PMCID: PMC10830446 DOI: 10.1042/bsr20231723] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 11/23/2023] [Accepted: 12/04/2023] [Indexed: 12/07/2023] Open
Abstract
The follicular helper T cells are derived from CD4+T cells, promoting the formation of germinal centers and assisting B cells to produce antibodies. This review describes the differentiation process of Tfh cells from the perspectives of the initiation, maturation, migration, efficacy, and subset classification of Tfh cells, and correlates it with autoimmune disease, to provide information for researchers to fully understand Tfh cells and provide further research ideas to manage immune-related diseases.

Klasse PJ, Ozorowski G, Sanders RW, Moore JP. Env Exceptionalism: Why Are HIV-1 Env Glycoproteins Atypical Immunogens? Cell Host Microbe 2020; 27:507-518. [PMID: 32272076 PMCID: PMC7187920 DOI: 10.1016/j.chom.2020.03.018] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2020] [Revised: 03/17/2020] [Accepted: 03/22/2020] [Indexed: 11/24/2022]
Abstract
Recombinant HIV-1 envelope (Env) glycoproteins of ever-increasing sophistication have been evaluated as vaccine candidates for over 30 years. Structurally defined mimics of native trimeric Env glycoproteins (e.g., SOSIP trimers) present multiple epitopes for broadly neutralizing antibodies (bNAbs) and their germline precursors, but elicitation of bNAbs remains elusive. Here, we argue that the interactions between Env and the immune system render it exceptional among viral vaccine antigens and hinder its immunogenicity in absolute and comparative terms. In other words, Env binds to CD4 on key immune cells and transduces signals that can compromise their function. Moreover, the extensive array of oligomannose glycans on Env shields peptidic B cell epitopes, impedes the presentation of T helper cell epitopes, and attracts mannose binding proteins, which could affect the antibody response. We suggest lines of research for assessing how to overcome obstacles that the exceptional features of Env impose on the creation of a successful HIV-1 vaccine.
