Brain-derived neurotrophic factor (BDNF) promotes maturation of cholinergic neurons. However, how activity-dependent BDNF expression affects specific cholinergic gene expression remains unclear. This study addressed this question by determining mRNA levels of 22 acetylcholine receptor subunits, the choline transporter (CHT), and the choline acetyltransferase (ChAT) in mice deficient in activity-dependent BDNF via promoter IV (KIV) and control wild-type mice. Quantitative RT-PCR revealed significant reductions in nicotinic acetylcholine receptor alpha 5 (CHRNA5) in the frontal cortex and hippocampus and M5 muscarinic acetylcholine receptor (CHRM5) in the hippocampus, but significant increases in M2 muscarinic acetylcholine receptor (CHRM2) in the frontal cortex of KIV mice compared to wild-type mice...

12/15 Lipoxygenase has recently been described as potent propagator of oxidative stress and is closely associated with cognitive decline in neurodegenerative diseases. The mechanism/s behind 12/15 LOX involvement in cognitive deficits remain obscure. The current study has been designed to investigate the underlying role of 12/15LOX and effect of 12/15 LOX inhibition on hypobaric hypoxia induced memory impairment and cholinergic deficits. Male Balb/c mice subjected to simulated hypobaric hypoxia/reoxygenation condition for 3 days showed marked working memory impairment concomitant with hippocampal neuronal damage and malondialdehyde production which were significantly attenuated by baicalein, a specific inhibitor of 12/15LOX...

BACKGROUND: Pediatric chronic kidney disease is psychologically, financially, and physically demanding on parents providing care. Parents often feel isolated because of the rarity of the condition, and geographic isolation often compounds this perception in Canada. Many parents seek assistance online for both information and social support. OBJECTIVE: This study examines an online portal, titled "Ability Online," which was designed to provide support and information to a diverse group of parents using chat facilities, bulletin boards, and e-mail...

Signal transducer and activator of transcription (STAT) proteins are activated by phosphorylation in the spinal cord of patients suffering from amyotrophic lateral sclerosis (ALS). The major scope of our study is a comprehensive histological characterization of the mechanisms underlying neuronal and glial STAT3 activation in the pathogenesis of ALS using SOD1(G93A) mice. We calculated the fold changes (FCs, ratios vs. appropriate controls) of the numerical densities of the following phosphorylated STAT3-positive (pSTAT3)(+) cells: choline acetyltransferase (ChAT)(+) α-motoneurons, ionized calcium-binding adapter molecule 1 (Iba1)(+) microglia, and S100β(+) astrocytes in SOD1(G93A) mice...

Single-nucleotide polymorphism (SNP)-based noninvasive prenatal testing (NIPT) can currently predict a subset of submicroscopic abnormalities associated with severe clinical manifestations. We retrospectively analyzed the performance of SNP-based NIPT in 80,449 referrals for 22q11.2 deletion syndrome and 42,326 referrals for 1p36, cri-du-chat, Prader-Willi, and Angelman microdeletion syndromes over a one-year period, and compared the original screening protocol with a revision that reflexively sequenced high-risk calls at a higher depth of read...

The nonneural cholinergic system of immune cells is pivotal for the maintenance of immunological homeostasis. Here we demonstrate the expression of choline acetyltransferase (ChAT) and cholinergic enzymes in murine natural killer (NK) cells. The capacity for acetylcholine synthesis by NK cells increased markedly under inflammatory conditions such as experimental autoimmune encephalomyelitis (EAE), in which ChAT expression escalated along with the maturation of NK cells. ChAT(+) and ChAT(-) NK cells displayed distinctive features in terms of cytotoxicity and chemokine/cytokine production...

Bacterial adhesion is a critical step for colonization of the host. The pioneer colonizer and commensal bacterium of the human gastrointestinal tract, Streptococcus salivarius, has strong adhesive properties but the molecular determinants of this adhesion remain uncharacterized. Serine-rich repeat (SRR) glycoproteins are a family of adhesins that fulfill an important role in adhesion. In general, Gram-positive bacterial genomes have a unique SRR glycoprotein-encoding gene. We demonstrate that S. salivarius expresses three large and glycosylated surface-exposed proteins - SrpA, SrpB and SrpC - that show characteristics of SRR glycoproteins and are secreted through the accessory SecA2/Y2 system...

The spider Cupiennius salei is a well-established model for investigating information processing in arthropod sensory systems. Immunohistochemistry has shown that several neurotransmitters exist in the C. salei nervous system, including GABA, glutamate, histamine, octopamine and FMRFamide, while electrophysiology has found functional roles for some of these transmitters. There is also evidence that acetylcholine (ACh) is present in some C. salei neurons but information about the distribution of cholinergic neurons in spider nervous systems is limited...

Introduction We investigated the interaction between adipose tissue derived stem cells (ASCs) and myoblasts in co-culture experiments. Methods Specific inductive media were used to differentiate ASCs in vitro into a Schwann cell-like phenotype (dASCs), and subsequently the expression of acetylcholine (ACh) related machinery was determined. Furthermore, the expression of muscarinic ACh receptors (mAChRs) was examined in denervated rat gastrocnemius muscles. Results In contrast to undifferentiated ASCs, dASCs expressed more choline acetyltransferase (ChAT) and vesicular acetylcholine transporter (VAChT)...

The digital revolution is turning lifestyles and mentalities upside down. The intuitiveness, immediacy and connectivity which characterise new information and communication technologies appeal to teenagers who find in them ways to gain recognition from their peers and to exchange with each other, without having to yield to adults. However, they expect mental health professionals to talk to them, to be engaged in their discussions and to agree to use connected tools as platforms for exchange. A wide variety of such methods can form part of the therapeutic relationship, from smartphones to chat rooms, from teleconsultations to 'cybertherapies', and from video games to serious games...

The incidence of brain degenerative disorders like Alzheimer's disease (AD) will increase as the world population ages. While there is presently no known cure for AD and current treatments having only a transient effect, an increasing number of publications indicate that growth factors (GF) may be used to treat AD. GFs like the bone morphogenetic proteins (BMPs), especially BMP-9, affect many aspects of AD. However, BMP-9 is a big protein that cannot readily cross the blood-brain barrier. We have therefore studied the effects of two small peptides derived from BMP-9 (pBMP-9 and SpBMP-9)...

Motoneurons are traditionally viewed as the output of the spinal cord that do not influence locomotor rhythmogenesis. We assessed the role of motoneuron firing during ongoing locomotor-like activity in neonatal mice expressing archaerhopsin-3 (Arch), halorhodopsin (eNpHR), or channelrhodopsin-2 (ChR2) in Choline acetyltransferase expressing neurons (ChAT(+)) or the LIM-homeodomain transcription factor Isl1(+) neurons. Illumination of the lumbar cord in mice expressing eNpHR or Arch in ChAT(+) or Isl1(+) neurons, depressed motoneuron discharge, transiently decreased the frequency, and perturbed the phasing of the locomotor-like rhythm...
