Levels of phospholipid-related metabolites of chronic lymphocytic leukemia lymphocytes (CLL) and normal human lymphocytes were quantified using phosphorus magnetic resonance spectroscopy. The CLL cells versus normal lymphocytes showed significant increases of phosphoethanolamine(Etn-P) (8.11+/-2.10 mean+/-S.E., micromol/g wet weight, n=12 versus 3.63+/-1.10, n=3, P

Autoimmune hepatitis (AIH) is a rare chronic inflammatory liver disease characterized by the presence of autoantibodies, including those targeting O-phosphoseryl-tRNA:selenocysteine-tRNA synthase (SepSecS), also known as soluble liver antigen (SLA). Anti-SepSecS antibodies have been associated with a more severe phenotype, suggesting a key role for the SepSecS autoantigen in AIH. To analyze the immune response to SepSecS in patients with AIH at the clonal level, we combined sensitive high-throughput screening assays with the isolation of monoclonal antibodies (mAbs) and T cell clones.

Leishmaniasis is a chronic inflammatory zoonotic illness caused by protozoan flagellates belonging to the genus. Current data suggest that over 1 billion people worldwide are susceptible to infection, primarily in tropical and subtropical countries, where up to 2 million new cases are reported annually. Therefore, the development of a vaccine is crucial to combating this disease.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse manifestations, requiring long-term treatment that can have side effects, particularly in pediatric patients. has shown potential for improving SLE symptoms due to its anti-inflammatory and immunomodulatory effects. The aim of this study was to investigate the immunomodulatory effect of oil (NSO) on disease activity, T lymphocyte activity and inflammatory cytokine profiles in pediatric SLE patients.

Dendritic cells are the most potent antigen-presenting cells in immune therapeutic approaches for chronic hepatitis B (CHB) infection. Here, we developed a clinical trial to evaluate the efficacy and safety of autologous HBV vaccine-pulsed DCs and their induced T cells (HPDCT) in CHB patients. This was a randomised, prospective, open-label, multicentre, superiority study and 309 treatment-naive CHB patients were divided into HPDCT plus nucleos(t)ide analogues (NAs) group (n = 84), NAs mono-therapy group (n = 82), HPDCT plus Peg-interferon (Peg-IFN) group (n = 69), Peg-IFN mono-therapy group (n = 74).
