Microglial dynamics during brain development
نویسندگان
چکیده
Microglia are the resident immune cells of the central nervous system (CNS). In the normal state, microglia have a ramified shape and continuously survey the conditions of the brain. In response to various stimuli, some microglia change to an amoeboid shape. This type of microglia is motile and produces several secretory proteins, including inflammatory cytokines and neurotrophic factors, which regulate brain homeostasis. Microglial morphology also changes a great deal in concert with environmental factors during brain development, and related to microglial migration and proliferation, which contribute to the establishment of precise synaptic connectivity and neural circuits. In this review, we focus on the fundamental concepts of microglial fate during brain development, and discuss whether the molecular mechanisms that control microglial morphology are linked to microglial functions.

Autism spectrum disorder (ASD) is a mental condition, present from early childhood, characterized by great difficulty in communicating and forming relationships with others and using language. In the last four decades many studies have shown that immune responses in different regions of brain play an important role in ASD pathogenicity. A conservative estimate based on the research suggests tha...

Microglia, the innate immune cells of the CNS, play a pivotal role in brain injury and disease. Microglia are extremely motile; their highly ramified processes constantly survey the brain parenchyma, and they respond promptly to brain damage with targeted process movement toward the injury site. Microglia play a key role in brain development and function by pruning synapses during development, ...

Microglia are the main resident immunocompetent cells of the brain with key roles in brain development, homeostasis and function. Here we briefly review our current knowledge of the homeostatic mechanisms regulating the composition and turnover of the microglial population under physiological conditions from development to ageing. A greater understanding of these mechanisms may inform understan...

Entrance of mesodermal precursors into the developing CNS is the most well-accepted origin of microglia. However, the contribution of proliferation and death of recruited microglial precursors to the final microglial cell population remains to be elucidated. To investigate microglial proliferation and apoptosis during development, we combined proliferating cell nuclear antigen (PCNA) immunohist...

Many diverse factors, ranging from stress to infections, can perturb brain homeostasis and alter the physiological activity of microglia, the immune cells of the central nervous system. Microglia play critical roles in the process of synaptic maturation and brain wiring during development. Any perturbation affecting microglial physiological function during critical developmental periods could r...
