[PMID: 38419796 PMCID: PMC10899404 DOI: 10.3389/fnmol.2024.1333842] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Accepted: 01/18/2024] [Indexed: 03/02/2024] Open
Abstract
Oxaliplatin, a platinum-based chemotherapy drug, causes neuropathic pain, yet effective pharmacological treatments are lacking. Previously, we showed that tetrandrine (TET), with anti-inflammatory properties, reduces mechanical allodynia in nerve-injured mice. This study explores the effect of TET on oxaliplatin-induced mechanical allodynia and gene changes in mice. Male C57BL/6J mice received oxaliplatin intraperitoneally to induce mechanical allodynia. Post-treatment with TET or vehicle, the mechanical withdrawal threshold (WMT) was assessed using von Frey filaments. TET alleviated oxaliplatin-induced mechanical allodynia. RNA sequencing identified 365 differentially expressed genes (DEGs) in the Control vs. Oxaliplatin group and 229 DEGs in the Oxaliplatin vs. TET group. Pearson correlation analysis of co-regulated DEGs and inflammation-related genes (IRGs) revealed 104 co-regulated inflammation-related genes (Co-IRGs) (|cor| > 0.8, P < 0.01). The top 30 genes in the PPI network were identified. Arg2, Cxcl12, H2-Q6, Kdr, and Nfkbia were highlighted based on ROC analysis. Subsequently, Arg2, Cxcl12, Kdr, and Nfkbia were further verified by qRCR. Immune infiltration analysis indicated increased follicular CD4 T cell infiltration in oxaliplatin-treated mice, reduced by TET. Molecular docking showed strong binding affinity between TET and proteins encoded by Arg2, Cxcl12, Kdr, and Nfkbia. In summary, TET may alleviate oxaliplatin-induced peripheral neuropathy in clinical conditions.

Stepwise differentiation of follicular helper T cells reveals distinct developmental and functional states. Nat Commun 2023; 14:7712.

Abstract
Follicular helper T (Tfh) cells are essential for the formation of high affinity antibodies after vaccination or infection. Although the signals responsible for initiating Tfh differentiation from naïve T cells have been studied, the signals controlling sequential developmental stages culminating in optimal effector function are not well understood. Here we use fate mapping strategies for the cytokine IL-21 to uncover sequential developmental stages of Tfh differentiation including a progenitor-like stage, a fully developed effector stage and a post-effector Tfh stage that maintains transcriptional and epigenetic features without IL-21 production. We find that progression through these stages are controlled intrinsically by the transcription factor FoxP1 and extrinsically by follicular regulatory T cells. Through selective deletion of Tfh stages, we show that these cells control antibody dynamics during distinct stages of the germinal center reaction in response to a SARS-CoV-2 vaccine. Together, these studies demonstrate the sequential phases of Tfh development and how they promote humoral immunity.

Zhang H, Sage PT. Role of T follicular helper and T follicular regulatory cells in antibody-mediated rejection: new therapeutic targets? Curr Opin Organ Transplant 2022; 27:371-375.

Abstract
PURPOSE OF REVIEW Antibody-mediated rejection (AbMR) after solid organ transplantation is tightly controlled by multiple cells of the immune system. Tfh and Tfr cells are essential controllers of antibody responses making them putative targets for therapeutics. However, the mechanisms of how Tfh and Tfr cells regulate B cell and antibody responses are not completely understood. Here, we summarize recent studies elucidating the functions of T follicular helper (Tfh) and T follicular regulatory (Tfr) cells as well as their possible roles in regulating AbMR in solid organ transplantation. RECENT FINDINGS New tools have been developed to study the roles of Tfh and Tfr cells in specific disease states, including AbMR after solid organ transplantation. These tools suggest complex roles for Tfh and Tfr cells in controlling antibody responses. Nevertheless, studies in solid organ transplant rejection suggest that Tfh and Tfr cells may be high value targets for therapeutics. However, specific strategies to target these cells are still being investigated. SUMMARY AbMR is still a substantial clinical problem that restricts long-term survival after solid organ transplantation. Growing evidence has demonstrated a pivotal role for Tfh and Tfr cells in controlling AbMR. In addition to providing an early indication of rejection as a biomarker, targeting Tfh and Tfr cells as a therapeutic strategy offers new hope for alleviating AbMR.
