A central criticism of standard theoretical approaches to constructing stable, recurrent model networks is that the synaptic connection weights need be finely-tuned. This severe because proposed rules for learning these have been shown various limitations their biological plausibility. Hence it unlikely such are used continuously fine-tune network in vivo. We describe a rule able tune biologically plausible manner. demonstrate and test this context oculomotor integrator, showing only known neural signals needed weights. appropriately accounts wide variety experimental results, robust under several kinds perturbation. Furthermore, we show achieve stability as good or better than provided by linearly optimal often models integrator. Finally, discuss how can generalized attractor networks, those found head direction path integration systems, suggesting may stable systems.

Background One of the main issues in pathogenesis MS is Th17/Treg imbalance. There are growing interests nominating miRNAs involved Th17 cell differentiation, suggesting them as new therapeutic agents that may reduce progression different autoimmune diseases specially MS. Objectives We assessed transcript levels miR-141 and miR-200a patients, during relapsing remitting phases. also investigated possible role miR-141, inducing differentiation to cells. Materials Methods Forty RR-MS patient samples including (n=20) phases were chosen. Expression level measured by RT-q PCR compared healthy control group (n=10). In-silico analyses on targetome showed involvement both T helper pathways TGF-β, mTOR JAK/STAT. Results observed percentage RORγt+ CD4+ cells increase phase while FOXP3+ patients. Furthermore, show up-regulation patients groups. Interestingly, expression target genes miR-200a, which through in-silico methods, down-regulation Conclusions According our results, be key symptoms inhibiting Treg Our data suggest these probably inhibit negative regulators thus promoting its differentiation.

Innervation of the bone marrow (BM) has been described more than one century ago, however first in vivo evidence that sympathoadrenergic fibers have a role hematopoiesis dates back to less 25 years ago. Evidence since increased showing adrenergic nerves BM release noradrenaline and possibly also dopamine, which act on adrenoceptors dopaminergic receptors expressed hematopoietic cells affect cell survival, proliferation, migration engraftment ability. Remarkably, dysregulation is associated with disturbances myeloproliferative disease. Several agents are already clinical use for non-hematological indications usually favourable risk-benefit profile, therefore potential candidates non-conventional modulation hematopoiesis.

Accumulation of aggregated amyloid-β (Aβ) peptide was studied as an initial step for Alzheimer's disease (AD) pathogenesis. Following amyloid plaque formation, reactive microglia and astrocytes accumulate around plaques cause neuroinflammation. Here brain chemokines play a major role the glial accumulation. We have previously shown that transgenic overexpression chemokine CCL2 in results increased microglial accumulation diffuse deposition mouse model AD expressing Swedish precursor protein (APP) mutant. Here, we report adeno-associated virus (AAV) serotype 1 2 hybrid efficiently deliver 7ND gene, dominant-negative mutant, dose–response manner express >1,000-fold higher recombinant than basal levels after single administration. AAV1/2 principally infected neurons without neuroinflammation with sustained expression 6-months. expressed APP/presenilin-1 (APP/PS1) bigenic mice reduced astro/microgliosis, β-amyloidosis, including suppression both fibrillar oligomer Aβ accumulation, improved spatial learning. Our data support idea system is useful tool CNS gene delivery, may be therapeutic target amelioration AD-related

This study examined associations between pandemic-related PTSD symptoms and substance use among adults, the role of gender socioeconomic status in these outcomes, supports that adults needed to address problems during Wave 1 COVID-19 pandemic Alberta, Canada.Data were collected from 933 community-based without a previous diagnosis June 2020. The Primary Care Screen was adapted assess symptoms. Participants asked if alcohol or cannabis had increased past month. Adjusted logistic regression models use.More women (19%) than men (13%) met criteria for high symptomology, while similar percentage (13.4% women, 13.2% men) reported significant increases pandemic. Adults 18-35 years; those who believed they would become infected with virus; low income, education, job loss more likely report High symptomology associated increase both (OR = 2.2) 2.3) adjusted models. Many (50% 40% help problems.Pandemic-related common COVID-19. These men. voiced need problems. Findings suggest interventions consider may be needed.

The DNA damage response (DDR) is a complex biological system activated by different types of damage. Mutations in certain components the DDR machinery can lead to genomic instability disorders that culminate tissue degeneration, premature aging, and various cancers. Intriguingly, malfunctioning plays role etiology late onset brain degenerative such as Parkinson's, Alzheimer's, Huntington's diseases. For many years, were thought result from aberrant neural death. Here we discuss evidence supports our novel hypothesis diseases involve dysfunction glial cells (astrocytes, microglia, oligodendrocytes). Impairment functionality results pathological neuro-glial interactions that, turn, generate "hostile" environment impairs neuronal cells. These events systematic demise on scale appears be proportional severity neurological deficit.
