The intensity of autoantibody production to red blood cell lysate in guinea pigs inoculated with smallpox vaccine prepared from different strains was studied at 7, 14, 21 and 28 days after vaccine inoculation. The dynamics of autoantibody production in the same animals as well as the influence of altered responsiveness of the animals pre-treated with dyphtheria toxin on the intensity of autoantibody production were determined. The autoantibody-inducing activity correlated with reactogenicity of the strains and was most marked in the white cloned variant of the Tashkent strain, slightly lower in the L-IVP strain being intermediate in this criterion and insignificant in poorly reactogenic EM-63 and B-51 strains. In the animals with altered responsiveness the autoimmune responses were increased. The results of this study were tested statistically.

Few pathogens have historically been subjected to as intense scientific and clinical scrutiny as SARS-CoV-2. The genetic, immunological, and environmental factors influencing disease severity and post-infection clinical outcomes, known as correlates of immunity, remain largely undefined. Clinical outcomes of SARS-CoV-2 infection vary widely, ranging from asymptomatic cases to those with life-threatening COVID-19 symptoms.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by dysregulated B cell activation, autoantibody production, and nephritis. B cell activating factor (BAFF) overexpression enhances autoreactive B-cell survival, driving autoimmunity. BAFF specific belimumab and CD20 specific rituximab antibodies are used for SLE therapy but are not curative, highlighting the need for alternative B cell depletion therapies.

Type 1 Diabetes (T1D) is an autoimmune disease mediated by autoreactive T cells. Our studies indicate that CD4 T cells reactive to Hybrid Insulin Peptides (HIPs) play a critical role in T cell-mediated beta-cell destruction. We have shown that HIPs form in human islets between fragments of the C-peptide and cleavage products of secretory granule proteins.

Background: Rheumatoid arthritis is a chronic autoimmune disease, progressively distinctive via cartilage destruction, auto-antibody production, severe joint pain, and synovial inflammation. Nanotechnology represents one of the utmost promising scientific technologies of the 21st century. Nanocarriers could be the key to unlocking its potential by encapsulating Rutin in targeted drug delivery systems, potentially for targeted Rheumatoid arthritis therapy.

Background: Determining esophageal and colon involvement in patients with Chagas disease occurs through invasive and uncomfortable examinations, which in most cases are not performed. The objective of this study was to assess the involvement of anti-M2-pyruvate kinase (M2-PK) autoantibodies in the development of digestive alterations and/or in the diagnosis of the digestive form of human Chagas disease.
Methods: The total IgG and isotype (IgG1, IgG2, IgG3, IgG4) production was quantified using the antigen of Trypanosoma cruzi and the human M2-PK recombinant protein via the ELISA technique.
