The hypothalamic–pituitary–adrenal(HPA) axis is a critical component of the neuroendocrine system,playing a central role in regulating the body's stress response and modulating various physiological processes. Dysregulation of HPA axis function disrupts the neuroendocrine equilibrium, resulting in impaired physiological functions. Acupuncture is recognized as a non-pharmacological type of therapy which has been confirmed to play an important role in modulating the HPA axis and thus favorably targets diseases with abnormal activation of the HPA axis. With numerous studies reporting the promising efficacy of acupuncture for neuroendocrine disorders, a comprehensive review in terms of the underlying molecular mechanism for acupuncture, especially in regulating the HPA axis, is currently in need. This review fills the need and summarizes recent breakthroughs, from the basic principles and the pathological changes of HPA axis dysfunction, to the molecular mechanisms by which acupuncture regulates the HPA axis. These mechanisms include the modulation of multiple neurotransmitters and their receptors, neuropeptides and their receptors, and microRNAs in the paraventricular nucleus,hippocampus, amygdala and pituitary gland, which alleviate the hyperfunctioning of the HPA *** review comprehensively summarizes the mechanism of acupuncture in regulating HPA axis dysfunction for the first time, providing new targets and prospects for further exploration of acupuncture.

The obligate biotrophic basidiomycete fungus Puccinia striformis ***(Pst)is the causative agent of wheat stripe(yellow)rust,a disease that results in severe damage to global wheat production(Chen and Kang,2017).This pathogen has a mixed reproductive mode encompassing both asexual and sexual *** asexual stage is accomplished by reinfecting wheat with urediniospores,while the sexual cycle involves five different spore types and two phylogenetically unrelated plant hosts wheat,which is the primary host,and barberry,which is the alternate host(Zhao et al.,2016).This extremely complex lifecycle facilitates large genetic variation among Pst populations,which is conducive to the emergence of new virulent races that can overcome wheat resistance genes,resulting in epidemics(Chen and Kang,2017).Secreted effector proteins,the key virulence factors in fungal pathogens,can not only suppress plant immune systems but also trigger host immune responses following recognition by plant receptors(Toruno et al.,2016).
