Article Abstract

Myocarditis is the common cause of sudden cardiac death, dilated cardiomyopathy (DCM) and heart failure (HF) in young adults. The most common type of myocarditis is viral myocarditis (VMC). Toll-like receptors (TLRs) are vital to identify pathogens . TLRs promote the differentiation of naive CD4T cells to T helper (Th) cells, activate the immune response, and participate in the pathogenesis of autoimmune and allergic diseases. Although the pathogenesis of VMC is unclear, autoimmune responses have been confirmed to play a significant role; hence, it could be inferred that VMC is closely related to TLRs and Th responses. Some drugs have been found to improve the prognosis of VMC by regulating the immune response through activated TLRs. In this review, we discuss the role of TLRs and Th responses in VMC.

Potential Impact of Extracorporeal Photopheresis on Trained Immunity and Organ Transplant Acceptance.

Extracorporeal photopheresis (ECP) is a well-established, safe, and effective immunomodulatory therapy currently used in clinics to decrease T cell-mediated immunity in various disorders, including autoimmune diseases and chronic rejection in organ transplantation. Although the ECP procedure has been shown to induce apoptotic cells that are reintroduced into the patient at the end of the treatment, the precise tolerogenic mechanisms mediated by ECP are not fully understood. Previous in vitro studies have demonstrated that early apoptotic cells express annexins on their cell surface, which suppress myeloid cell activation on stimulation with bacterial lipopolysaccharide through Toll-like receptors.

Microglial cells are key mediators of ethanol-induced neuroinflammation through the release of proinflammatory cytokines and activation of Toll-like receptors. Recently, the signaling pathway initiated by the interaction of the neurotrophic factors pleiotrophin (PTN) and midkine (MK) with receptor-type protein tyrosine phosphatase β/ζ (RPTPβ/ζ) has emerged as a pharmacological target in ethanol-induced neuroinflammatory and neurodegenerative processes. However, the underlying molecular mechanisms remain unclear.

Recent studies suggested that treating sperm with R848, a ligand for the X-linked Toll-like receptors 7 and 8 (TLR7/8) in mice, goats, and cattle, could selectively reduce the motility of X chromosome bearing sperm (X-sperm). This reduction enables the separation of X- and Y-sperm and thereby sex selection. However, through three species and multiple methods, our results challenged prior published data.

Background/aims: Ubiquitin D (UBD), a member of the ubiquitin-like modifier (UBL) family, is significantly overexpressed in various cancers and is positively correlated with tumor progression. However, the role and underlying mechanisms of UBD in rheumatoid arthritis (RA) remain poorly understood. This study aimed to investigate the effects of UBD knockdown on the progression of RA.
