A 66 year-old male patient with rheumatoid arthritis, was admitted due to bronchial pneumonia. Anti-nuclear antibody and anti-DNA antibody were both detected in the patient's serum and many LE-like cells were found in the pleural effusion. In addition, M-proteins(IgG-kappa type, IgM-kappa type) were detected in both serum and pleural effusion by immunofixation electrophoresis. Purified IgG fraction by gel filtration(Superdex 200HR) showed high titer of anti-nuclear antibody(x160) and anti-DNA(39.2 AU/ml) antibody. Furthermore, anti-DNA antibody was detected in the fraction III(fraction of M-protein) by ion-exchange chromatography. In conclusion, these results indicate that M-protein(IgG3-kappa type) contains anti-DNA antibody and it is suggests that M-protein induces the production of LE like cell in this case.

BI 1703880, a novel STimulator of INterferon Genes (STING) agonist, has demonstrated preclinical antitumor activity. As STING activation can upregulate programmed death ligand 1 and human leukocyte antigen in tumor cells, a combination of BI 1703880 and an anti-programmed cell death protein 1-antibody, such as ezabenlimab, may improve efficacy. This first-in-human phase Ia study (NCT05471856) is evaluating BI 1703880 plus ezabenlimab in patients with advanced solid tumors.

Background: Patients with systemic lupus erythematosus (SLE) are susceptible to infectious diseases owing to various immunosuppressive treatments and disease characteristics. Meningococcal infections progress rapidly with a high incidence of severe complications and mortality; therefore, meningococcal vaccination is needed. However, there is limited evidence regarding the immunity and immunogenicity of patients with SLE.

Background: Positivity for anti-gp210 and anti-centromeric antibodies (ACA) in patients with primary biliary cholangitis (PBC) have been associated with the progression of liver failure and portal hypertension (PH), respectively. The value of combining risk autoantibody assessments with prognostic scoring systems in improving risk assessment in patients with PBC remains unclear.
Aims: To investigate the prognostic significance of various combinations of anti-gp210 and ACA statuses and their enhancing the prognostic utility on the GLOBE scoring system.

Lipid nanoparticles (LNPs) for mRNA delivery have advanced significantly, but LNP-mediated DNA delivery still faces clinical challenges. This study compared various LNP formulations for delivering DNA-encoded biologics, assessing their expression efficacy and the protective immunity generated by LNP-encapsulated DNA in different models. The LNP formulation used in Moderna's Spikevax mRNA vaccine (LNP-M) demonstrated a stable nanoparticle structure, high expression efficiency, and low toxicity.

This study presents a new highly sensitive and specific time-resolved fluoroimmunoassay (TRFIA) for the measurement of trace amounts of the urinary 8-hydroxy-2`-deoxyguanosine (8-OHdG) which is a biomarker for oxidative stress on DNA. The assay relied on a competitive binding approach and a mouse monoclonal antibody which recognized 8-OHdG with high specificity. In this assay, 8-OHdG conjugated with bovine serum albumin protein (8-OHdG-BSA) was employed as a solid phase antigen.
