It is postulated that organ-specific autoimmune diseases could be initiated by dysregulated peripherally activated monocytes/macrophages penetrating into target organs nonspecifically. Failure of regulation of pro-inflammatory monocytes/macrophages might then result in autoimmune disease if secondary over-expansion of pre-existing autoantigen-specific T cell populations occurs in genetically predisposed individuals.

Doxorubicin is a highly effective anticancer agent, but its clinical use is restricted by severe side effects, including atherosclerosis and cardiomyopathy. These complications are partly attributed to doxorubicin's ability to induce endothelial-to-mesenchymal transition (EndMT) in vascular endothelial cells, a critical process in the initiation and progression of atherosclerosis and cardiomyopathy. GV1001, a multifunctional peptide with anti-inflammatory, anti-cancer, antioxidant, and anti-Alzheimer's properties, has demonstrated inhibition of EndMT.

Weeds are a concern in agriculture and the use of herbicides constitutes an effective, efficient, and economical way to control their growth. Recent discoveries of herbicides are promising for the management of resistant weeds. However, there is a gap in the knowledge of the toxic effects of some herbicides previously reported on immune cells.

Background: Tongue squamous cell carcinoma (TSCC) is a malignant oral cancer with unclear pathogenesis that shows a tendency for early-stage lymphatic metastasis. This results in a poor prognosis, with a low 5-year survival rate. Dietary sodium nitrite (NaNO) has proposed associations with disease, including cancer.

The innate immune system plays an important role in the defense against pathogens, whereby the ability to rapidly mount an effective inflammatory response is critical in the elimination/containment of the infection. To better understand the nature of the inflammatory responses to bacterial components in chickens, we used the growing feather (GF) cutaneous bioassay together with blood sampling to examine the local and systemic inflammatory responses initiated by intradermal (i.d.

Article Synopsis
  • Antiretroviral therapy (ART) helps suppress HIV but doesn't fully normalize cytokine levels; long-term effects of ART on these immune markers haven't been thoroughly researched.
  • A study tracked 31 men and 59 women on ART for an average of 6 years, measuring changes in 40 cytokines/chemokines, finding that while most stayed stable, certain markers decreased over time, while others increased.
  • Results showed sex and race differences in specific cytokine levels, with women exhibiting higher innate immune activation; overall, ART may reduce inflammation and lower the risk of diseases related to cardiovascular health.
