Infants exhibit diminished susceptibility to external infections， a phenomenon closely linked to the pervasive presence of the bifidobacterial community within their intestinal tract. Nonetheless， a significant knowledge gap remains concerning the distinct species of bifidobacteria initiating anti-infection immune responses during the early developmental stages. In this study， the impact of early intervention with Bifidobacterium bifidum (B. bifidum)， B. breve， and B. longum on neonatal rats infected with Salmonella enterica serovar Typhimurium (S. typhimurium) SL1344 were compared. The study encompasses various immunity levels， including gut immunity， central immunity (thymus)， peripheral immunity (spleen)， and brain immunity. Following Salmonella infection， significant alterations in neonatal rats were observed in growth and developmental levels， immune markers， cytokine levels， balance of T lymphocyte subpopulations， intestinal barrier function， and blood-brain barrier integrity. Compared with B. breve and B. longum， B. bifidum demonstrated more pronounced efficacy in regulating these physiological processes. By conducting multi-level analyses of gut microbiota， bifidobacterial community， colonic content metabolomics， and serum metabolomics， the significance of B. bifidum's role is underscored， and the immune-enhancing function of messenger metabolites is unveiled. Among these metabolites， γ-L-Glutamyl-L-glutamic acid and Orotic acid were found to be shared by all three species， while Hippuric acid and 1a，1b-dihomo Prostaglandin F2α were unique to B. bifidum， and DL-Arginine was specific to B. longum. Overall， this study has provided novel insights into the intervention and immunomodulation by Bifidobacterium in early-life infections， emphasizing the significant role of B. bifidum.

Endogenous opioid antinociception is a self-regulatory mechanism that reduces chronic pain, but its underlying circuit mechanism remains largely unknown. Here, we showed that endogenous opioid antinociception required the activation of mu-opioid receptors（MORs） in GABAergic neurons of the central amygdala nucleus（CEA） in a persistent-hyperalgesia mouse model. Pharmacogenetic suppression of these CEAMORneurons, which mimics the effect of MOR activation, alleviated the persistent ***, single-neuron projection analysis revealed multiple projectome-based subtypes of CEAMORneurons, each innervating distinct target brain regions. We found that the suppression of axon branches projecting to the parabrachial nucleus（PB） of one subtype of CEAMORneurons alleviated persistent hyperalgesia, indicating a subtype-and axonal-branch-specific mechanism of action. Further electrophysiological analysis revealed that suppression of a distinct CEA-PB disinhibitory circuit controlled endogenous opioid antinociception. Thus, this study identified the central neural circuit that underlies endogenous opioid antinociception, providing new insight into the endogenous pain modulatory mechanisms.
