in the regulation of cell development, and are specifically important
in synapse formation, axon guidance and neuronal differentiation.
Eroglu's earlier work has shown that thrombospondins are released by brain cells called astrocytes and boost new
synapse formation between neurons
in the brain.
MHCI limits
synapse density by inhibiting insulin receptors, which regulate the body's sugar metabolism and,

synapse formation and distribution
in dendrites has been challenging due to a lack of reliable methods that trigger and monitor
synapse formation.
A new study just published
in the journal Glia and available online on July 11th, details the newly discovered mechanism by which astrocytes are involved
in inhibitory
synapse formation and presents strong evidence that Transforming Growth Factor Beta 1 (TGF β1), a protein produced by many cell types (including astrocytes) is a key player
in this process.

In summary, our results demonstrate that PKN1 functions as a developmentally active gatekeeper of AKT activity, thereby fine - tuning axonal outgrowth and presynaptic differentiation of Cgcs and subsequently the correct PF - PC
synapse formation.
Dr. Parsons has shown that while there is some degree of tonic endocannabinoid
formation in the brain, an overt influence of endocannabinoid signaling requires
synapse - specific activation of endocannabinoid
formation.

in immune
synapse formation and IL - 2 production.

in dictating
synapse formation and function via the release of specific proteins that determine the type of
synapse that will form, and the strength of that
synapse.

in hippocampal slices indicated acute synaptic loss, followed by
synapse formation and maintenance phases.
For example, our discovery of HORMAD1 (Fig 2) and HORMAD2, two proteins that preferentially associate with unpaired / unsynapsed meiotic chromosome cores / axes, allowed us to address how progression
in meiosis is coordinated with crossover
formation, and how meiotic checkpoints / quality control ensure that only those meiocytes progress
in meiosis that correctly paired and
synapsed their homologous chromosomes.

in synapse formation you saw.
