Membrane microparticles (MMP) released from apoptotic cells deliver signals that secure the anti-inflammatory response beyond the nearest proximity of the apoptotic cell. Plasmacytoid dendritic cells (pDC) are sentinels prepared to detect cellular processes that endanger the organism. They play a key role in the regulation of both pro- and anti-inflammatory immune responses. Based on the assump...
We have previously shown that CD32A (or FcgammaRIIA), one of the main opsonin receptors, was rapidly insolubilized and degraded in intact neutrophils after its cross-linking. In view of these experimental difficulties, the early signalling steps in response to CD32A activation were studied in purified plasma membranes of neutrophils. After CD32A cross-linking in these fractions, the tyrosine ph...
Neutrophils express 2 low-affinity FcgammaR, FcgammaRIIIB (CD16B), and FcgammaRIIA (CD32A). CD16B is a glycosyl-phosphatidyl inositol-anchored molecule, whereas CD32A is a polypeptide-anchored molecule. These 2 receptors also differ in their signaling. The biological significance of coexpression of 2 FcgammaRs with distinct membrane anchors and signaling capacities is not clearly understood. Us...
کلزا یکی از گیاهان مهم روغنی می باشد که تنها بعد از سویا و نخل روغنی جایگاه سوم را در تولید جهانی به خود اختصاص داده است. این گیاه عضو خانواده براسیکا می باشد. یکی از مهمترین عوامل محدود کننده تولید دانه های روغنی از جمله کلزا مجموعه ای از آفات هستند که به این گیاه خسارت وارد می کنند. آفات حشره ای گیاهان روغنی کلزا، منحصراً مختص خانواده شب بو هستند که از جمله این آفات، آفات پروانه ای می باشند. آ...
BACKGROUND The Fcgamma receptors play important roles in anti-glomerular basement membrane antibody disease (anti-GBM disease) in animal models, and FCGR gene polymorphisms have been reported to be associated with numerous human autoimmune diseases. We aimed to clarify the genetic association of FCGR gene polymorphisms with anti-GBM disease in Chinese patients. METHODS A total of 48 patients ...
BACKGROUND Malignant B-cell clones are affected by both acquired genetic alterations and by inherited genetic variations changing the inflammatory tumour microenvironment. METHODS We investigated 50 inflammatory response gene polymorphisms in 355 B-cell non-Hodgkin's lymphoma (B-NHL) samples encompassing 216 diffuse large B cell lymphoma (DLBCL) and 139 follicular lymphoma (FL) and 307 contro...
