Global cerebral ischemia induces selective degeneration of specific subsets of neurons throughout the brain, particularly in the hippocampus and cortex. One of the major hallmarks of cerebral ischemia is excitotoxicity, characterized by overactivation of

Identification of the Calmodulin-Binding Domains of Fas Death Receptor
The extrinsic apoptotic pathway is initiated by binding of a Fas ligand to the ectodomain of the surface death receptor Fas protein. Subsequently, the intracellular death domain of Fas (FasDD) and that of the Fas-associated protein (FADD) interact to form the core of the death-inducing signaling complex (DISC), a crucial step for activation of caspases

The Roles of Coinhibitory Receptors in Pathogenesis of Human Retroviral Infections
Costimulatory and coinhibitory receptors play a key role in regulating immune responses to infection and cancer. Coinhibitory receptors include programmed cell death 1 (PD-1), cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), and T cell ...

Evidence for a function of death-receptor-related, death-domain-containing proteins in anoikis [PDF]
Normal epithelial cells undergo apoptosis if integrinmediated matrix contacts are lost, in a process termed 'anoikis'. Anoikis prevents shed epithelial cells from colonizing elsewhere, and is thus essential for maintaining appropriate tissue organisation. Aberrant oncogenes or tumor suppressor genes can cause resistance to anoikis, thereby contributing

Rice XB15, a protein phosphatase 2C, negatively regulates cell death and XA21-mediated innate immunity. [PDF]
Perception of extracellular signals by cell surface receptors is of central importance to eukaryotic development and immunity. Kinases that are associated with the receptors or are part of the receptors themselves modulate signaling through ...

Assembly of Oligomeric Death Domain Complexes during Toll Receptor Signaling [PDF]
The Drosophila Toll receptor is activated by the endogenous protein ligand Spätzle in response to microbial stimuli in immunity and spatial cues during embryonic development. Downstream signaling is mediated by the adaptor proteins Tube, the kinase Pelle, and the Drosophila homologue of myeloid differentiation primary response protein (dMyD88). Here we

ABSTRACT We assessed the effect of iron overload (IO) on mortality and complications following hematopoietic stem cell transplantation (HSCT) in patients with Diamond–Blackfan anemia syndrome (DBAS) in a systematic review of individual participant data and cohort data from observational studies.

Structural and functional investigation of the cytoplasmic domain of the Fas death receptor [PDF]
Activation of the transmembrane death receptor Fas (CD95/APO-1) by a membrane bound ligand (FasL/CD95L) activates the extrinsic pathway of apoptosis. Intracellular Fas death domains (DDs) are induced to oligomerise enabling binding to the adaptor protein

Ligand-binding domain determines endoplasmic reticulum exit of AMPA receptors.
AMPA receptors (AMPARs) are tetrameric ion channels that mediate rapid glutamate signaling in neurons and many non-neuronal cell types. Endoplasmic reticulum (ER) quality control mechanisms permit only correctly folded functional receptors to be ...

New Insights into VacA Intoxication Mediated through Its Cell Surface Receptors
Helicobacter pylori (H. pylori), a major cause of gastroduodenal diseases, produces VacA, a vacuolating cytotoxin associated with gastric inflammation and ulceration.
