BTK is a critical mediator of survival in B cell neoplasms. While BTK inhibitors have transformed therapy in CLL, high genetic risk patients are at risk for relapse and have a poor prognosis. Identification of novel therapeutic strategies for this group of patients is an urgent unmet clinical need, and therapies that target BTK via alternative mechanisms may fill this niche. Herein, we identify a set of miRNAs that target BTK in primary CLL cells and show that the HDAC repressor complex is recruited to these miRNA promoters to silence their expression...

Central nervous system (CNS) injuries and diseases result in neuronal damage, and loss of function. Transplantation of neural stem cells (NSCs) has been shown to improve locomotor function after transplantation. However, due to the immune and inflammatory response at the injury site, the survival rate of the engrafted cells is low. Engrafted cell viability has been shown to increase when transplanted within a hydrogel. Hyaluronic acid (HA) hydrogels have natural anti-inflammatory properties and the backbone can be modified to introduce bioactive agents, such as anti-Fas, which we have previously shown to promote NSC survival while suppressing immune cell activity in bulk hydrogels in vitro...

Neuroinflammation, a common neuropathologic feature of neurodegenerative disorders including Parkinson disease (PD), is frequently exacerbated by microglial activation. The extracellular protein α-synuclein (ASYN), whose aggregation is characteristic of PD, remains a key therapeutic target, but the control of synuclein trafficking and aggregation within microglia has been challenging. First, we established that microglial internalization of monomeric ASYN was mediated by scavenger receptors (SR), CD36 and SRA1, and was rapidly accompanied by the formation of ASYN oligomers...

INTRODUCTION: Over the past three decades, the number of people with diabetes mellitus (DM) has more than doubled globally, making it one of the most important public health challenges to all nations. Aldose reductase (AR) is a rate-limiting enzyme in the polyol pathway, which has been implicated in the pathogenesis of diabetic microvascular complications; however, the association of the AR gene with diabetic macrovascular complications has rarely been investigated. AIM: The study aimed to identify the possible association between C(-106) T polymorphism of the AR gene and diabetic macroangiopathy in a cohort of Egyptian patients with type 2 DM...

Phosphorylation of many aminoacyl tRNA synthetases (AARSs) has been recognized for decades, but the contribution of post-translational modification to their primary role in tRNA charging and decryption of genetic code remains unclear. In contrast, phosphorylation is essential for performance of diverse noncanonical functions of AARSs unrelated to protein synthesis. Phosphorylation of glutamyl-prolyl tRNA synthetase (EPRS) has been investigated extensively in our laboratory for more than a decade, and has served as an archetype for studies of other AARSs...

Hepatitis C virus (HCV) is the leading cause of liver fibrosis and hepatocellular carcinoma (HCC). At present, there is no predictive biomarker for the patients at high risk of developing HCC. In this study, we examined the association between single-nucleotide polymorphisms (SNPs) in 3 innate immunity genes [2'-5'oligoadenylate synthetase 1 (OAS1) rs10774671, interleukin 28B (IL28B) rs12979860, and low molecular mass polypeptide 7 (LMP-7) at codon 49] besides cytomegalovirus (CMV) coinfection and susceptibility to HCC in genotype 4 (GT4) chronically infected Egyptian patients...

Full T-cell activation requires interaction between the costimulatory receptors B7-2 and CD28. By binding CD28, bacterial superantigens elicit harmful inflammatory cytokine overexpression through an unknown mechanism. We show that, by engaging not only CD28 but also its coligand B7-2 directly, superantigens potently enhance the avidity between B7-2 and CD28, inducing thereby T-cell hyperactivation. Using the same 12-aa β-strand-hinge-α-helix domain, superantigens engage both B7-2 and CD28 at their homodimer interfaces, areas remote from where these coreceptors interact, implying that inflammatory signaling can be controlled through the receptor homodimer interfaces...

BACKGROUND: Cyclosporine A (CsA)-induced nephrotoxicity is a challenging problem complicating its chronic use in a large array of autoimmune diseases, as well as in organ transplantation. A considerable body of evidence points to the involvement of nitric oxide (NO) and its endogenous synthesis inhibitor, asymmetric dimethylarginine (ADMA), in CsA-induced renal and cardiovascular adverse effects. In this study, the potential of the third generation β-blocker, nebivolol, to modify the NO/ADMA system is hypothesized to play a role in protection against CsA-induced renal injury and endothelial dysfunction...

Pituitary adenoma (PA) is one of the most common abnormalities in the sellar region. Despite the fact that PA is a benign monoclonal neoplasm, it can cause serious complications, including ophthalmological, neurological and endocrinological abnormalities. Currently, the causes that increase the progression of tumors are unknown. Epigenetic silencing of the matrix metalloproteinase-14 (MMP-14) and transforming growth factor beta-1 (TGFβ-1) genes may be associated with the development of PA, since these genes are important in the processes of tumor metastasis and angiogenesis...

Diabetic retinopathy is one of the serious complications of diabetes and the leading cause of decreased vision and blindness worldwide. Neurodegeneration has been recognized as initiating factor in causing the retinal damage, which leads to micro-vascular damage in diabetic retinopathy. Diabetes-induced oxidative stress is believed to be the key factor that damages neurons in the diabetic retina. Various therapeutic approaches for effective attenuation of increased oxidative stress by antioxidants have emerged...
