A three base-pair deletion in the widely expressed TOR1A gene causes childhood onset, neurological disease of DYT1 dystonia. Mouse Tor1a knockout also specifically affects developing nervous system. However, both cases, basis neuronal tissue specificity is unknown. TorsinA one four predicted mammalian torsin ATPases associated with assorted cellular activities (AAA+) proteins, raising possibility that expression a functionally homologous compensates for torsinA loss non-neuronal tissues.

Different models of learning health systems are emerging. At Vanderbilt University Medical Center, the Learning Health Care System (LHS) Platform was established with goal creating generalizable knowledge. This differentiates LHS from other efforts that have adopted a quality improvement paradigm. By supporting pragmatic trials at intersection research, operations, and clinical care, designed to yield evidence for advancing content processes care through carefully designed, rigorous study....

TorsinA (also known as torsin-1A) is a membrane-embedded AAA+ ATPase that has an important role in the nuclear envelope lumen. However, most torsinA localized peripheral endoplasmic reticulum (ER) lumen where it slow mobility incompatible with free equilibration between ER subdomains. We now find nuclear-envelope-localized present on inner membrane (INM) and ask how reaches this subdomain. The system contains two transmembrane proteins, LAP1 LULL1 TOR1AIP1 TOR1AIP2, respectively), reversibly...

Introduction Patients with suspected bacterial infection frequently receive empiric, broad-spectrum antibiotics prior to pathogen identification due the time required for bacteria grow in culture. Direct-from-blood diagnostics identifying presence or absence of and/or resistance genes from whole blood samples within hours collection could enable earlier antibiotic optimisation patients have infections. However, few randomised trials evaluated effect using direct-from-blood testing on...

Synaptogenesis requires orchestrated intercellular communication between synaptic partners, with trans-synaptic signals necessarily traversing the extracellular synaptomatrix separating presynaptic and postsynaptic cells. Extracellular matrix metalloproteinases (Mmps) regulated by secreted tissue inhibitors of (Timps), cleave membrane-associated targets to sculpt environment modulate signaling. Here, we test roles Mmp at neuromuscular junction (NMJ) model synapse in reductionist Drosophila...

Neural development requires N-glycosylation regulation of intercellular signaling, but the requirements in synaptogenesis have not been well tested. All complex and hybrid MGAT1 (UDP-GlcNAc:α-3-D-mannoside-β1,2-N-acetylglucosaminyl-transferase I) function, Mgat1 nulls are most compromised condition that survive long enough to permit studies. At Drosophila neuromuscular junction (NMJ), mutants display selective loss lectin-defined carbohydrates extracellular synaptomatrix, an accompanying...

ABSTRACT Congenital disorders of glycosylation (CDGs) constitute a rapidly growing family human diseases resulting from heritable mutations in genes driving the production and modification glycoproteins. The symptomatic hypoglycosylation causes multisystemic defects that include severe neurological impairments, revealing particularly critical requirement for tightly regulated nervous system. most common CDG, CDG-Ia (PMM2-CDG), arises phosphomannomutase type 2 (PMM2) mutations. Here, we...

Matrix metalloproteinase (MMP) functions modulate synapse formation and activity-dependent plasticity. Aberrant MMP activity is implicated in fragile X syndrome (FXS), a disease caused by the loss of RNA-binding protein FMRP characterized neurological dysfunction intellectual disability. Gene expression studies Drosophila suggest that Mmps cooperate with heparan sulfate proteoglycan (HSPG) glypican co-receptor Dally-like (Dlp) to restrict trans-synaptic Wnt signaling synaptogenic defects fly...

When infectious organisms unknown, patients treated with empiric antibiotics to include coverage for gram-negative organisms, such as antipseudomonal cephalosporins and penicillins. However, observational studies, some (eg, cefepime) associated neurologic dysfunction while most common penicillin (piperacillin–tazobactam) is acute kidney injury (AKI). No randomised control trials have compared these regimens. This...
