Involvement of CD226+ NK Cells in Immunopathogenesis of Systemic Lupus Erythematosus

Involvement of CD226+ NK cells in immunopathogenesis of systemic lupus erythematosus.

Dysfunction of immune systems, including innate and adaptive immunity, is responsible for the immunopathogenesis of systemic lupus erythematosus (SLE). NK cells are a major part of the innate immune system, and diminished populations of NK cells have been reported in SLE patients. However, the mechanisms behind this decrease and the role of NK cells in SLE pathogenesis remain poorly understood....

P 137: Central Nervous System Involvement in Systemic Lupus Erythematosus

Systemic Lupus Erythematosus (SLE) is a complex clinical syndrome which its components are less clearly recognized and includes heterogeneous demonstrations engaging both central and peripheral nervous system along with disabling effects. This disease is called "thousand faces" due to these heterogeneous demonstrations. This gap exists while 75% of adults and children with SLE may dea...

Neurobrucellosis in systemic lupus erythematosus

Background: Brucellosis is a zoonotic infection which is endemic in many countries. It is a multisystem disease which may present with a broad spectrum of clinical manifestations and complications. Neurobrucellosis is an uncommon complication of brucellosis. Case presentation: A 25-year-old woman with a history of lupus for 5 months referred to the emergency ward of Shahid Beheshti Hosp...

CD226 expression deficiency causes high sensitivity to apoptosis in NK T cells from patients with systemic lupus erythematosus.

Humans and mice with systemic lupus erythematosus (SLE) and related autoimmune diseases have reduced numbers of NK T cells. An association between NK T cell deficiency and autoimmune disease has been identified. However, the mechanisms for reduction of NK T cell number in patients with SLE are unknown. In the present study we report that NK T cells from active SLE patients are highly sensitive ...
