Abstract:
:Studies have suggested that heightened neuroinflammation contributes to the pathogenesis of depressive disorder. A major participant in neuroinflammation is microglia, and fractalkine signaling (which comprises the chemokine CX3CL1, mainly expressed by neurons, and its receptor CX3CR1, almost exclusively present on microglia in healthy brains) has been reported to critically regulate microglial activity. The aim of this study was to investigate whether CX3CR1 deficiency was associated with a different outcome following chronic unpredictable stress (CUS) and the possible mechanism. Wild-type (WT) and CX3CR1-deficient (CX3CR1-/-) mice were subjected to CUS for 3 weeks. CX3CR1-/- mice displayed a better performance through sucrose preference test, open field test and forced swim test, which demonstrated that CX3CR1 deficiency alleviated depressive-like disturbances, such as anhedonia, anxiety or hopelessness. Nevertheless, CX3CR1-/- mice also showed less severe cognitive impairment from the results of Morris Water Maze and Novel object recognition. Long-term potentiation was recorded to test the synaptic plasticity and its result was consistent with that of cognitive ability tests. Both results of real time-PCR and immunofluorescence staining demonstrated that CX3CR1 deficiency facilitated the alternative activation of microglia, thus attenuated the release of inflammatory cytokines, which was verified by ELISA and flow cytometry. Maybe due to the mitigated neuroinflammation, CX3CR1-deficient mice showed higher resilience to CUS-induced blood brain barrier hyperpermeability and loss of dendrite spine (as showed by Golgi and DiI staining) than WT group. All of above results indicated that hampering neuron-microglia communication via CX3CR1-CX3CL1 pathway attenuated the effects of CUS on depressive-like disturbances and cognitive impairment.

Behavioural Brain Research is an international, interdisciplinary journal dedicated to the publication of articles in the field of behavioural neuroscience, broadly defined. Contributions from the entire range of disciplines that comprise the neurosciences, behavioural sciences or cognitive sciences are appropriate, as long as the goal is to delineate the neural mechanisms underlying behaviour. Thus, studies may range from neurophysiological, neuroanatomical, neurochemical or neuropharmacological analysis of brain-behaviour relations, including the use of molecular genetic or behavioural genetic approaches, to studies that involve the use of brain imaging techniques, to neuroethological studies. Reports of original research, of major methodological advances, or of novel conceptual approaches are all encouraged. The journal will also consider critical reviews on selected topics.
《行为大脑研究》是一本国际性、跨学科的期刊,专门发表广义上的行为神经科学领域的文章。只要目标是描述行为背后的神经机制,来自包括神经科学、行为科学或认知科学在内的整个学科领域的贡献都是合适的。因此,研究范围可能从神经生理学、神经解剖学、神经化学或神经药理学分析脑行为关系,包括使用分子遗传学或行为遗传学方法,到涉及使用脑成像技术的研究,到神经行为学研究。报告的原始研究,主要方法的进步,或新的概念方法都是鼓励。该杂志还将考虑对选定主题的评论。
