Lactobacillus rhamnosus reduces CD8T cell mediated inflammation in patients with rheumatoid arthritis.

Background: The T cells, components of adaptive immunity participate in immune pathology of the autoimmune inflammatory disorder called rheumatoid arthritis (RA). The presence of TLRs on the surface of the CD8 T cells and their ability to recognize bacterial moieties adds to the inflammatory burden in case of RA. It has been reported that the gut microbiome is necessary for the crucial shift in the balance between proinflammatory and anti-inflammatory cytokines.

Toll-like receptor-7 activation in CD8+ T cells modulates inflammatory mediators in patients with rheumatoid arthritis.

Rheumatoid arthritis (RA) is an autoimmune disorder of unknown etiology with aberrant immunological responses leading to inflammation, swelling and pain of the joints. CD8 T cells have been known to be one of the major immune modulators in the progression of RA and the presence of toll-like receptors (TLRs) on these cells further accentuate their role in RA. Herein, we report an increased expression of TLR7 in the endosomes of CD8 T cells of RA patients correlating with disease severity.

Understanding the Role and Uses of Alternative Therapies for the Management of Rheumatoid Arthritis.

With the growing popularity of complementary and alternative medicine (CAM) among individuals with chronic pain and muscular problems, a number of patients with rheumatoid arthritis (RA) show their interest in CAM interventions for disease improvement. Various reports published on CAM are based on an animal model of RA; however, there is often a lack of high-quality clinical investigations for explaining the success stories of CAM therapies in patients with RA. CAMs having the potential to be used for therapy in patients with RA have been identified, however lack of awareness and skepticism of their efficacy has made the patients reluctant to choose these drug-less therapies.

The COVID-19 pandemic: an increased risk of rheumatoid arthritis.

COVID-19 is a respiratory infection similar to viral pneumonia and is caused by SARS-CoV-2. Chloroquine and hydroxychloroquine make up the major part of the treatment regimen for the management of COVID-19 infections, which are also commonly used in treatment of patients with malaria as well as autoimmune diseases like rheumatoid arthritis (RA). In this review, we analyzed the scientific evidences pertaining to any possible association of SARS-CoV-2 infection with RA.

Increased Extracellular ATP in Plasma of Rheumatoid Arthritis Patients Activates CD8T Cells.

Background: Rheumatoid arthritis (RA) is an autoimmune disorder with genetic and environmental causes often linked with the disease etiology. A disrupted metabolism has often been a characteristic of RA and an altered metabolic state of immune cells has been associated with their phenotypic and functional changes. The energy in the form of ATP produced by the metabolically active cells may thus initiate a cascade of immune responses there by influencing the disease pathogenesis or progression.
