This study examined (1) the extent to which a history of CM investigation was associated with changes in youth high-sensitivity C-reactive protein (hs-CRP) and body mass index (BMI) across a two-year period, and (2) the moderating role of social support from different sources (caregivers, siblings, and peers) on this association. Participants included 318 youth (ages 8–13, 49.7 % female, 72 % white, 82.7 % with past CM investigation) who completed baseline (Time 1) and two-year follow up (Time 2) visits. CM history, hs-CRP and BMI were assessed at T1. Caregiver, peer, and sibling support, hs-CRP, and BMI were assessed at T2. Adjusting for youth age, sex, race/ethnicity, household income, and hs-CRP and BMI at Time 1, no main effects of CM history on Time 2 hs-CRP or BMI were found (<em>p</em>s > 0.28). However, independent of CM history, greater peer support was associated with lower BMI at Time 2 (β = -0.10, <em>p</em> = 0.005). Peer support further moderated the association between CM history and Time 2 BMI (β = -0.16, <em>p</em> = 0.007), such that CM history was associated with higher BMI only when peer support was relatively lower. Additionally, independent of CM history, greater sibling support was associated with lower hs-CRP at Time 2 (β = -0.09, <em>p</em> = 0.03). Post-hoc sensitivity analyses suggested unique effects when considering the number of types of CM experienced. Experiencing more types of CM was associated with greater Time 2 hs-CRP only when peer support was relatively lower (β = 0.07, <em>p</em> = 0.048). Additionally, youth who experienced more types of CM and who had higher levels of sibling support showed lower Time 2 hs-CRP (β = -0.15, <em>p</em> = 0.03). Overall, findings suggest that independent of CM history, greater sibling and peer support were associated with lower hs-CRP and BMI across a two-year period. Although there were no main effects of CM, greater peer support buffered the longitudinal effects of CM history on youth BMI.

Despite ongoing research, therapeutic options for this disorder remain inadequate. Here, we report that neurotrophin-3 (<em>Nt3</em>) mRNA and its encoded proneurotrophin-3 (proNT3) protein are upregulated in neurons of the injured dorsal root ganglion (DRG), but not in the spinal cord, following peripheral nerve trauma. Mature neurotrophin-3 (NT3) protein is undetectable in the DRG under both normal and nerve trauma conditions. Genetic blockage of <em>Nt3</em> mRNA/proNT3 protein upregulation in the injured DRG attenuates the development and maintenance of nerve trauma-induced neuropathic pain, without impacting acute/basal pain responses or locomotor function. Conversely, mimicking nerve trauma-induced upregulation of DRG <em>Nt3</em> mRNA/pro-NT3 produces neuropathic pain-like symptoms. These symptoms are mitigated by intrathecal injection of NT3 protein or by selective knockdown of tropomyosin receptor kinase C (TrkC), but not TrkA or TrkB, in the DRG. Notably, intrathecal injection of NT3 also alleviates nerve trauma-induced neuropathic pain.

However, current understanding of the temporal progression of these pathological changes in the context of neuroinflammation and chronic cognitive outcomes is limited. This study characterized temporospatial changes in the hilar region of the DG, showing that the population of reelin- and somatostatin-expressing inhibitory interneurons was significantly reduced as early as 7 days post-injury (dpi), and that aberrant migration of excitatory granule cells occurs gradually in the weeks to months following injury. These findings coincided with upregulation of monocyte/macrophage-associated inflammatory mediators, including MIP-1β, MIG, MCP-1, and TNF-α at 7 days dpi, with differential cytokine regulation persisting 120 dpi. Injury was associated with the development of chronic spatial memory impairment and reduced risk-assessment behavior, with a transient reduction in spontaneous anxiety. TNFR1 and TNFR2 were differentially expressed in inhibitory neurons, further implicating TNF-signaling as a driver of hilar neuron loss. Furthermore, systemic administration of anti-TNF-α monoclonal antibody induced significant neuroprotection, attenuated pro-inflammatory mediators, and hilar interneuron loss.

Cumulative evidence reveal obesity impairs hippocampal synaptic plasticity and induces neuronal apoptosis. Leucine rich repeat containing 4 (LRRC4) is a member of the Netrin G ligand (NGL) family, and plays a crucial role in maintaining neuronal morphology, function, and structure of synapses. However, it remains unclear whether LRRC4 affects obesity-induced cognitive impairment or its underlying mechanism. Herein, we showed that a high-fat diet (HFD) led to cognitive deficits in obese mice, as assessed by the Morris water maze and Nest building tests. The expression of LRRC4 and postsynaptic dense protein 95 (PSD-95) was downregulated in the hippocampus of mice with HFD-fed obesity. Furthermore, the effects of LRRC4 overexpression (AAV-LRRC4) and knockout (<em>Lrrc4<sup>−/−</sup></em>, deletion location: 28,831,753–28,828,926) on neurological function and synapses were investigated. Data from behavioral and electrophysiological studies demonstrated that LRRC4 knockout impaired synaptic plasticity and resulted in cognitive impairment in mice. Moreover, the expression level of PSD-95 was further decreased in <em>Lrrc4<sup>−/−</sup></em>mice fed by HFD. Meanwhile, the expression of the anti-apoptotic protein Bcl-2 was decreased, whereas the levels of the pro-apoptotic proteins cleaved-caspase 3 and BAX were increased in the hippocampus of HFD <em>Lrrc4<sup>−/−</sup></em> mice. This indicated that <em>Lrrc4</em> knockout exacerbated neuronal injury and apoptosis. Overexpression of LRRC4 in the hippocampus of HFD mice, ameliorated the behavioral abnormalities of HFD mice and strengthened synaptic transmission. In parallel, Golgi staining displayed a significant increase in the length and number of dendritic branches of neurons. Additionally, LRRC4 overexpression promoted PSD-95 expression and exerted an anti-apoptotic effect, as evidenced by the upregulation of Bcl-2 and downregulation of cleaved caspase-3 and BAX in the hippocampus. These findings suggest that LRRC4 enhances synaptic function and alleviates neuronal injury in HFD mice.
