Summary The plant endosphere is colonized by complex microbial communities and microorganisms, which colonize the interior at least part of their lifetime are termed endophytes. Their functions range from mutualism to pathogenicity. All organs tissues generally bacterial endophytes diversity composition depend on plant, organ its physiological conditions, growth stage as well environment. Plant‐associated in particular endophytes, have lately received high attention, because increasing awareness importance host‐associated microbiota for functioning performance host. Some endophyte known mostly lab assays, genome prediction few metagenome analyses; however, we limited understanding planta activities, particularly considering micro‐environments dynamics conditions. In our review, present recent findings environments, conditions colonization. Furthermore, discuss functions, interaction between plants methodological limitations research. We also provide an outlook needs future research improve role colonizing traits ecosystem functioning.

Chronic neuroinflammation with sustained microglial activation occurs following severe traumatic brain injury (TBI) and is believed to contribute subsequent neurodegeneration neurological deficits. Microglia, the primary innate immune cells in brain, are dependent on colony stimulating factor 1 receptor (CSF1R) signaling for their survival. In this preclinical study, we examined effects of delayed depletion chronically activated microglia functional recovery up 3 months postinjury. A CSF1R inhibitor, Plexxikon (PLX) 5622, was administered adult male C57BL/6J mice at month after controlled cortical impact remove microglia, inhibitor withdrawn 1-week later allow repopulation. Following TBI, repopulated displayed a ramified morphology similar that Sham uninjured mice, whereas vehicle-treated TBI showed typical chronic posttraumatic hypertrophic morphology. PLX5622 treatment limited TBI-associated neuropathological changes postinjury; these included smaller lesion, reduced hippocampal neuron cell death, decreased NOX2- NLRP3 inflammasome-associated neuroinflammation. Furthermore, led widespread transcriptome altered gene pathways involved neuroinflammation, oxidative stress, neuroplasticity. Using variety complementary neurobehavioral tests, PLX5622-treated also had improved long-term motor cognitive function through Together, studies demonstrate phase removal neurotoxic using inhibitors markedly reduce associated neurodegeneration, as well related SIGNIFICANCE STATEMENT Traumatic debilitating disorder can seriously patient's quality life. Microglial-mediated induced contributes deficits on-going neurodegenerative processes. Here, investigated effect breaking neuroinflammatory loop 1-month by pharmacological 5622. Overall, show short-term elimination during followed repopulation results improvements function, suppression stress pathways, reduction persistent These clinically relevant support new concepts therapeutic window may be far longer than traditionally if evolving microglial-mediated inhibited or regulated precise manner.
