Article Synopsis
  • The study reviews the use of monoclonal antibodies (Mabs) in treating Graves Orbitopathy (GO), analyzing their development, naming, and rationale behind their usage.
  • A systematic review identified 76 relevant articles out of 954 screened, focusing mainly on Rituximab, Tocilizumab, and Teprotumumab, while noting that only a few clinical trials directly compared these Mabs against traditional treatments.
  • The conclusion indicates uncertainty regarding the safest and most effective Mab for GO, due to the lack of direct comparisons, varying relapse rates, potential side effects, and high costs associated with these treatments.

We describe two cases of extensive indolent calvarial osteomyelitis after rhino-orbital-mucormycosis in diabetic patients previously diagnosed with COVID-19. Both patients presented with acute rhino-orbital symptoms about one month after being diagnosed with COVID-19. Treatment with intravenous liposomal Amphotericin B and prompt radical surgical debridement was instituted, but calvarial osteomyelitis ensued and persisted chronically despite maintenance of antifungal therapy and partial debridement of necrotic calvarial bone.

Background: P2X7 receptors (P2X7R) are ligand-gated ion channels activated by adenosine 5'-triphosphate (ATP), which are involved in processes that are dysfunctional in stress response and depression, such as neurotransmitter release, and neuroimmune response. Genetic and pharmacological inhibition of the P2X7R induce antidepressant-like effects in animals exposed to stress. However, the effect of P2X7R antagonism in an animal model of depression based on selective breeding has not previously been studied, and the mechanism underling the antidepressant-like effect induced by the P2X7R blockade remains unknown.

Recent evidence indicates that nonprofessional immune cells such as epithelial cells, endothelial cells, and fibroblasts also contribute to innate immunity via secretion of cytokines. Fibroblasts are the principal type of cell found in the periodontal connective tissues and they are involved in the immune response during periodontal disease. The role of fibroblasts in the recognition of pathogens via Toll-like receptors (TLRs) has been established; however, few studies have been conducted concerning the involvement of innate immune receptors in the recognition of Candida albicans by gingival fibroblast.

Squamous cell carcinoma (SCC) is one of the most common human cancers worldwide. Recent studies show that regulatory T cells (Treg) have a critical role in the modulation of an antitumor immune response, and consequently the SCC development. Because the accumulation of Tregs at the tumor site is, in part, due to selective recruitment through CCR5- and CCR5-associated chemokines, we investigated the role of CCR5 in the SCC development.
