Integrin CD11b, which is cd11b by Itgamis expressed on the surface of macrophages and has been implicated in cd11b, migration, and cell-mediated cytotoxicity.

Lupus nephritis LN is a common complication of systemic lupus erythematosus SLE with unclear etiology and limited treatment options. Immune cell infiltration into the kidneys, a hallmark of LN, triggers tissue damage and proteinuria. CD11b modulates several key biological functions in innate immune cells, including cell adhesion, migration, and phagocytosis. CD11b also modulates other signaling pathways in these cells, such as the Toll-like receptor signaling pathways, that mediate generation of type I interferons, a key proinflammatory cytokine and circulating biomarker in SLE and LN patients. However, how variants in ITGAM gene contribute to disease pathogenesis has not been completely established. Here, we provide an overview of CD11b modulated mechanisms and the functional consequences of the genetic variants that can drive disease pathogenesis. We also present recent insights from studies after pharmacological activation of CD11b. These studies offer novel mechanisms for development of therapeutics for LN, SLE and other autoimmune diseases. Lupus nephritis LN is an inflammatory kidney disease that is a common complication of systemic lupus erythematosus SLE , an autoimmune disease that affects women nine times more often than men and is characterized by aberrant autoimmune responses to self-antigens that can result in multiple end organ pathologies. There is considerable variation in the prevalence of SLE and the frequency of LN in different regions of the world and different races and ethnicities [reviewed in Ref.

The development of easily accessible tools for human immunophenotyping to classify patients into discrete disease endotypes is advancing personalized therapy.

Erbo Christensen, S. Pravsgaard Christensen, A. Based on their activation state T cells can be subdivided into naive, effector and memory subsets. Naive T cells are resting cells that have not yet encountered antigen, whereas effector T cells are recently activated cells able to perform specialized functions with high efficiency and without further differentiation. Immunological memory is the capacity of the immune system to respond faster and more efficiently against an antigen previously encountered by the host 1. The mechanisms underlying the accelerated secondary response appear to be both an increased number of antigen-specific T cells and a qualitative change in T cells that have already been primed by antigen contact 2 — 5.

The clinical use of morphine may be accompanied by increased immunosuppression, susceptibility to infection and postoperative tumor metastatic recurrence, and the specific mechanisms and clinical strategies to alleviate this suppression remain to be investigated. Expression of CD11b is closely associated with the macrophage phagocytosis of xenobiotic particles, bacteria or tumor cells. Here, we find that morphine at 0.

Article Google Scholar Jaeschke, H. Comment This field is required. PMID One hundred microliters of the culture medium were incubated with equal amount of Griess reagent Promega, Madison, WI, USA at room temperature for 10 min, and the absorbance was measured at nm using a microplate reader. Future studies will determine how well such a strategy is able to ameliorate disease in LN patients.
