The inwardly rectifying potassium (Kir) channel subunit Kir4.1 is specifically expressed in brain astrocytes and Kir4.1-containing channels (Kir4.1 channels) mediate astroglial spatial potassium (K + ) buffering. Recent advances in Kir4.1 research revealed that Kir4.1 channels can serve as a novel therapeutic target for epilepsy. Specifically, reduced expression or dysfunction of Kir4.1 channel...
Cation channel gating may occur either at or below the inner vestibule entrance or at the selectivity filter. To differentiate these possibilities in inward rectifier (Kir) channels, we examined cysteine accessibility in the ATP-gated Kir6.2 channel. MTSEA and MTSET both block channels and modify M2 cysteines with identical voltage dependence. If entry is restricted to open channels, modificati...
Background: Interaction between killer cell immunoglobulin-like receptors (KIR) and human leukocyte antigen (HLA) class I molecules is important for regulation of natural killer (NK) cell function. Objective: The aim of this study was to investigate the impact of compound KIR-HLA genotype on susceptibility to acute leukemia. Methods: Cohorts of Iranian patients with acute myeloid leukemia (AML;...
Glutamate uptake, mediated by electrogenic glutamate transporters largely localized in astrocytes, is responsible for the clearance of glutamate released during excitatory synaptic transmission. Glutamate uptake also determines the availability of glutamate for extrasynaptic glutamate receptors. The efficiency of glutamate uptake is commonly estimated from the amplitude of transporter current r...
Purpose: In 2010, a Children's Oncology Group (COG) phase III randomized trial for patients with high-risk neuroblastoma (ANBL0032) demonstrated improved event-free survival (EFS) and overall survival (OS) following treatment with an immunotherapy regimen of dinutuximab, GM-CSF, IL2, and isotretinoin compared with treatment with isotretinoin alone. Dinutuximab, a chimeric anti-GD2 monoclonal an...
Inwardly rectifying potassium (Kir) channels are prime determinants of resting membrane potential in neurons. Their subcellular distribution and surface density thus help shape neuronal excitability, yet mechanisms governing the membrane targeting and localization of Kir channels are poorly understood. Here we report a direct interaction between the strong inward rectifier, Kir2.1, and a recent...
A potential factor influencing hematopoietic stem cells transplantation (HSCT) outcome is the presence of donor-derived alloreactive natural killer (NK) cells. This retrospective analysis studied the impact of NK alloreactivity based on the missing KIR ligand, for acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) patients undergoing non-T-cell depleted HLA-identical sibling HS...
Molecular biology has shown there to be a great diversity of potassium channel isoforms. Among the simplest structurally are the inward rectifier potassium channel, KCNJ gene family. These channels are open in the region of the resting potential, a potential that they therefore help to determine. Some 14 genes are known for this family, classified into 7 subfamilies in terms of sequence homolog...
