Transmembrane AMPA receptor regulatory proteins (TARPs) govern AMPA receptor cell surface expression and distinct physiological properties including agonist affinity, desensitization and deactivation kinetics. The prototypical TARP, STG or γ2 and TARPs γ3, γ4, γ7 and γ8 are all expressed to varying degrees in the mammalian brain and differentially regulate AMPAR gating parameters. Positive allosteric AMPA receptor modulators or ampakines alter receptor rates of agonist binding/unbinding, channel opening and can offset receptor desensitization and deactivation...

The G-protein-coupled receptor kinase 2 (GRK2) plays a major role in cardiovascular diseases and its expression is increased in heart failure. However, only little is known about factors being involved in up-regulation of GRK2 expression through transcriptional regulation of its promoter. Since the transcription factor early-growth response 1 (EGR-1) is also up-regulated in patients with heart failure, we tested the hypothesis that EGR-1 regulates GRK2 transcription. Stimulation of immortalized rat cardiomyocytes (H9c2) with phorbol 12-myristate 13-acetate (PMA) resulted in up-regulation of Egr-1 and subsequently of Grk2 mRNA expression, with maximum Grk2 expression (p=0...

PURPOSE OF REVIEW: Tuberculosis (TB) is the commonest infectious cause of death globally. Adverse reactions to first-line tuberculosis antibiotics are common and have a major impact on the outcomes of patients as second-line antibiotics are less effective and more toxic. The present review addresses the most recent literature regarding epidemiology, investigating reactions, and reintroducing treatment in patients who have had their treatment interrupted. RECENT FINDINGS: Studies have demonstrated that up to 60% of patients experience adverse reactions to TB treatment; around a third of these are idiosyncratic and may relate to immune sensitization...

Glioblastoma multiforme (GBM) is a highly aggressive brain cancer and its survival after diagnosis is less than 2 years. Therefore, GBM patients are especially prone to co-occurring psychological conditions such as anxiety and depressive disorders. Furthermore, aggressive medical therapies affect patients' lives, undermining their sense of meaning and coherence. The main aim of this study was to determine the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) therapy on anxiety, depression and sense of coherence in patients with GBM...

The ability of pregnanolone glutamate (PA-Glu), pregnanolone hemisuccinate (PA-hSuc) and pregnanolone hemipimelate (PA-hPim), neuroactive steroids with a negative modulatory effect on excitatory N-methyl-d-aspartate receptors, to influence the functional activity of inhibitory γ-aminobutyric acid and glycine receptors was estimated. The GABA- and glycine-induced chloride currents (IGABA and IGly ) were measured in isolated pyramidal neurons of the rat hippocampus using the patch-clamp technique. Compound PA-Glu was found to potentiate IGABA and to inhibit IGly , while PA-hSuc and PA-hPim inhibited both IGABA and IGly ...

Like in other sensory systems, adaptation is an essential process in the olfactory system, required for its proper functioning. However, the precise molecular mechanism underlying the adaptation process has not been fully understood, especially at the receptor level. Here, we describe methods to evaluate the role of GRK3, one of the members of the GRK family responsible for the desensitization of non-olfactory G-protein-coupled receptor (GPCR), in desensitization of olfactory receptor (OR) using a heterologous expression system...

ABO-incompatible (ABOi) kidney transplantation represents a viable tool to increase the donor pool for kidney transplantation, however, increased alloimmune response has been debated. The early outcomes of 25 low-risk ABOi kidney transplant recipients were compared with thoroughly matched 50 ABO-compatible (ABOc) ones. The matching process was based on gender and age of recipients and immunologic parameters, such as panel reactive antibodies, number of human leukocyte antigen mismatches, and transplantation era...

Bendamustine, an alkylating agent with cytotoxic properties, has been increasingly employed in the treatment of chronic lymphocytic leukemia (CLL) either as a single agent or combination with rituximab. Although rarely reported, they can potentially cause hypersensitivity reactions with serious consequences. The objective of the case report was to offer a safe and effective bendamustine desensitization protocol to patients with a hypersensitivity reaction to this drug. We report a case of a patient with a CLL who developed a type IV hypersensitivity reaction to bendamustine and who was successfully treated by drug desensitization...

Arrestins regulate the signaling of ligand-activated, phosphorylated G-protein-coupled receptors (GPCRs). Different patterns of receptor phosphorylation (phosphorylation barcode) can modulate arrestin conformations, resulting in distinct functional outcomes (for example, desensitization, internalization, and downstream signaling). However, the mechanism of arrestin activation and how distinct receptor phosphorylation patterns could induce different conformational changes on arrestin are not fully understood...
