Laura Mackay highlights seminal studies that shed light on tissue immunity and the unique biology of tissue-resident memory T cells.

objectives the cause of rheumatoid arthritis (ra) as a chronic inflammatory autoimmune disease is still unknown. it appears that both genetic and environmental factors play a role in its pathogenesis. recent studies reveal that in addition to the cns, immune cells synthesis neurotransmitters so that these catecholamines can regulate immune functions. the aim of this study is to evaluate the dop...

human t-lymphotropic virus type i (htlv-1) is an endemic virus in iran and other regions that is associated with multiple diseases including adult t-cell leukemia/ lymphoma and a chronic debilitating neuroinflammatory disease, htlv-1-associated myelopathy/tropical spastic paraparesis (ham/tsp). ham/tsp is seen in approximately 2% of htlv-1-infected people with symptoms such as back pain, weakne...

background: type 2 diabetes (t2d) is a chronic metabolic disorder in which beta-cells are destroyed. the islet amyloid polypeptide (iapp) produced by beta-cells has been reported to influence beta-cell destruction. objective: to evaluate if iapp can act as an autoantigen and therefore, to see if cd8 + t-cells specific for this protein might be present in t2d patients. methods: peripheral blood ...

patients and methods in this cross-sectional study, peripheral mononuclear cells (pbmcs) were isolated from peripheral blood of 29 patients with newly diagnosed pulmonary tb and 19 patients with positive tuberculin skin test. the pbmcs were activated with ppd for 72 hours. activated cells were harvested, rna was extracted and cdna was synthesized. a real-time taqman method was designed and opti...

Background. We have previously shown that nitrogenous metabolites immunomodulatory effects, both in healthy rats and humans exposed to pathogenic influences. The purpose of this study is their immunotropic activity clinically people. Materials Methods. object observation were 27 men (aged 24-63 ys) 14 women (33-62 ys). plasma levels the parameters immunity twice with an interval 5 days was perf...
