Objective: Endogenous retroelements (EREs) stimulate type 1 interferon (IFN-I) production but have not been explored as potential interferonogenic triggers in rheumatoid arthritis (RA). We investigated ERE expression in early RA (eRA), a period in which IFN-I levels are increased.
Methods: ERE expression (long terminal repeat [LTR] 5, long interspersed nuclear element 1 [LINE-1], and short interspersed nuclear element [SINE]) in disease-modifying treatment-naïve eRA whole-blood and bulk synovial tissue samples was examined by reverse transcription-polymerase chain reaction and NanoString alongside IFN-α activity.
Autoantibodies against cytokines (c-aAb) have been implicated in the pathophysiology of autoimmune diseases, and a variety of infections. In addition, several independent studies have detected elevated titers of c-aAb in the circulation of healthy individuals. To further understand their impact on immune responses, we measured c-aAb against IFN-α, IFN-γ, CSF2, IL-1α, IL-6, and IL-10 in the plasma of 1000 healthy individuals of the Milieu Intérieur (MI) cohort.

- HIV infection leads to gastrointestinal mucosal damage, which affects microbial balance and immune response, leading to non-infectious comorbidities in people living with HIV (PLWH).
- A study measured zonulin levels in serum and intestinal tissue from HIV-infected individuals and controls, revealing higher levels of zonulin in the bloodstream of HIV patients, but lower levels in their gut tissue compared to controls.
- Elevated systemic zonulin was linked to the loss of intestinal CD4 T cells and increased gut inflammation, suggesting a relationship between zonulin and intestinal health that could be important for managing comorbidities in PLWH.
Article Synopsis
- Hereditary C1q deficiency (C1QDef) is a rare genetic disorder that disrupts the complement system and can cause symptoms similar to systemic lupus erythematosus (SLE).
- A study of 12 genetically confirmed C1QDef patients showed elevated expression of interferon-stimulated genes and high levels of interferon alpha in their blood and cerebrospinal fluid, indicating significant immune dysfunction.
- Treatment with Janus-kinase inhibitors had mixed results, with one patient improving while others continued to struggle with their condition, highlighting the complexity of managing C1QDef.
