Low-dose Interleukin-2 in the Treatment of Autoimmune Disease | touchONCOLOGY - 0 views

  • affect approximately 5 to 8 % of the US population
  • the incidence and prevalence of autoimmune diseases are rising
  • Type 1 diabetes (T1D), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and inflammatory bowel disease (IBD) account for the majority of the patients with autoimmune diseases
  • ...9 more annotations...
  • Autoimmune diseases are characterized by a breakdown of mechanisms that allow the immune system to distinguish between self and nonself and maintain immunologic self-tolerance
  • Tregs, which are important in the maintenance of peripheral immune tolerance.
  • Several subtypes of Tregs exist, the most well studied being CD4+ cells that express high-level CD25 and the transcription factor forkhead box P3 (FOXP3)
  • Treg deficiency or dysfunction is associated with autoimmune disease
  • In clinical studies, decreased levels of circulating CD25+CD4+ T cells have been reported in patients with autoimmune disease
  • These data have led to the hypothesis that augmentation of Tregs may be a useful therapeutic strategy in autoimmune disease
  • Treg augmentation has resulted in clinical improvements in numerous animal models of autoimmune diseases
  • the administration of in vitro expanded CD4+CD25highCD127-Tregs has been found to be safe and may help to preserve β-cell function in children with T1D
  • ability of IL-2 to augment the numbers and function of CD4+ Tregs.
  •  
    Great article.  Immune dysfunction plays role in autoimmune disease and cancer.  Treg cells sit at the center of autoimmunity.  This artice highlights the different uses: low dose IL2 therapy to augment Tregs and reduce autoinflammation and high dose IL2 to augment Treg cells in the fight against cancer.

Autoimmune Hypogonadism as Part of an Autoimmune Polyglandular Syndrome - 0 views

  •  
    autoimmune hypogonadism is a common cause of hypogonadism in those with autoimmune polyglandular syndrome.  This is rare outside APS-1.

Immune Modulation in Multiple Sclerosis Patients Treated with the Pregnancy Hormone Est... - 0 views

  • A beneficial effect of pregnancy on clinical symptoms has been observed in MS and other Th1-mediated autoimmune diseases, including rheumatoid arthritis (RA), psoriasis, uveitis, and thyroiditis
  • In general, Th1 lymphocytes secrete proinflammatory cytokines (e.g., IL-2, IL-12, IFN-γ, and TNF-α) that promote cellular immunity, while Th2 lymphocytes produce anti-inflammatory cytokines (e.g., IL-4, IL-5, IL-6, and IL-10) that promote humoral immunity
  • Th2 cytokines are associated with the down-regulation of Th1 cytokines and may confer protection from Th1-mediated autoimmune diseases
  • ...1 more annotation...
  • During pregnancy, there is a shift from Th1 to Th2 that occurs both locally, at the fetal maternal interface, (23, 24, 25), and systemically
  •  
    MS is in part a Th1 autoimmune disease.  Estriol therapy induces a shift to Th2 through increase in Th10.  Estriol also decreases TNF-alpha cytokine production.

Autoimmunity and Heavy Metals - 0 views

  • Gold may cause autoimmune thrombocytopenia, immune complex-mediated glomerulonephritis and other autoimmune disorders
  • there is solid evidence that mercury can induce autoimmune disease both in humans and experimental animals.
  •  
    Heavy metals cause some autoimmune diseases

Estriol and Progesterone: A New Role for Sex Hormones - 0 views

  • Pregnancy-associated Th2 shift has been proposed as a mechanism underlying the improvement of Th1-mediated autoimmune diseases (as rheumatoid arthritis, multiple sclerosis (MS), autoimmune thyoriditis, uveitis, and psoriatic arthritis
  • Th2-mediated autoimmune diseases (as systemic lupus erythematosus)
  • During pregnancy PRG serum level increases by a factor of 4, while estrogen estriol (E3) serum concentration increases by a factor of 20
  • ...1 more annotation...
  • In pregnant women at or near term there is a daily production of about 300 μmol (80 mg) of E3 and 1 mmol (300 mg) of PRG
  •  
    Estriol and Progesterone associated, as found with pregnancy, associated with decrease in Th1 autoimmune disease.

Global Academy for Medical Education: Gut inflammation linked to worsening spondyloarth... - 0 views

  •  
    Just a press release, but gut inflammation is associated with increased early treatment in those with autoimmune spondyloarthritis compared to those without gut inflammation.  Inflammation clearly plays a role in all autoimmune disease.

Potential Therapeutic Effects of Curcumin, the Anti-inflammatory Agent, Against Neurode... - 0 views

  • The starting dose was 500 mg/day and if no toxicity was noted, the dose was then escalated to another level in the order of 1,000, 2,000, 4,000, 8,000, and 12,000 mg/day. There was no treatment-related toxicity up to 8 g/day but the bulky volume of the drug was unacceptable to the patients beyond 8 g/day.
  • The serum concentration of curcumin usually peaked at 1 to 2 hours after oral intake of curcumin and gradually declined within 12 hours
  •  
    Great article on the benefits of curcumin in therapy for inflammation and disease.

  •  
    Vitamin D support provides benefit in those with Lupus.  The proposed mechanism is through the balance of Treg cells and Th17 cells.  This imbalance plays a role in the etiology of autoimmune disease and those with autoimmune disease, such as in Lupus, frequently have low vitamin D levels.
