The development of easily accessible tools for human immunophenotyping to classify patients into discrete disease endotypes is advancing personalized therapy. However, no systematic approach has been developed for the study of inflammatory lung diseases with often complex and highly heterogeneous disease etiologies. We have devised an internally standardized flow cytometry approach that can identify parallel inflammatory alveolar macrophage phenotypes in both the mouse and human lungs.

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. LN severity also differs among the ethnicities with more renal involvement in individuals of African lineage, Hispanics, and Asian populations 4 — 6. The discrepancies between ancestral backgrounds could be due to the complex interplay between genetic and environmental risk factors that drives kidney inflammation in LN. These factors could compromise mechanisms that normally assure immune tolerance to nuclear autoantigens leading to the activation and proliferation of immune cells, including monocytes, autoreactive B and T cells that are recruited to the kidney tissue where they produce destructive cytokines and chemokines, which in turn attract more infiltrating cells.

Blood ; 18 : — A consistently increased mRNA expression of the adhesion receptor CD11b is a hallmark of the reported genomewide gene expression changes in precursor B-cell acute lymphoblastic leukemia PBC-ALL after 1 week of induction therapy. To investigate its clinical relevance, CD11b protein expression in leukemic blasts has been prospectively measured at diagnosis patients and during therapy 53 patients. CD11b positivity conferred a 5-fold increased risk of minimal residual disease MRD after induction therapy day 33 and of high-risk group assignment after consolidation therapy day In the multivariate analysis CD11b expression was an independent prognostic factor compared with other clinically relevant parameters at diagnosis. Microarray-based gene expression profiling is a powerful tool for basic research, target discovery, and identification of novel molecular biomarkers.

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.

DAPI blue was used to stain nucleus. Description of Additional Supplementary Files. As LA1 has also been shown to inhibit bone marrow derived cell trafficking to tissues by promoting stable adhesion to endothelium. The heterozygous mutant mice were generated using the blastocyst injection method. One of them are myeloid-derived suppressor cells MDSC and tumour-associated macrophages TAMs , which are myeloid cells present in the tumour microenvironment possessing suppressor properties, thus favouring the tumour growth. CD11b regulates antibody class switching via induction of AID. I agree to the terms and conditions. Importantly, transient siRNA-mediated knockdown of CD11b in in vitro cultured macrophages elevated immune suppressive gene expression and decreased immune stimulatory gene expression, effects that are comparable to CD11b deletion Fig. Proposals for the immunological classification of acute leukemias.
