Cannabinoid Control of Gingival Immune Activation in Chronically SIV-Infected Rhesus Macaques Involves Modulation of the Indoleamine-2,3-Dioxygenase-1 Pathway and Salivary Microbiome

HIV-associated periodontal disease (PD) affects people living with HIV (PLWH) on combination anti-retroviral therapy (cART). Researchers used a systems biology approach to investigate the molecular, metabolome, and microbiome changes underlying PD and its modulation by phytocannabinoids (Δ9-THC) in rhesus macaques. Δ9-THC reduced IDO1 protein expression. The findings suggest that phytocannabinoids may help reduce gingival/systemic inflammation, salivary dysbiosis, and potentially metabolic disease in PLWH on cART.

Western-Style Diet Consumption Impairs Maternal Insulin Sensitivity and Glucose Metabolism During Pregnancy in a Japanese Macaque Model

Using a Japanese macaque model, investigators assessed the metabolic effects of obesity and a calorically dense, Western-style diet (WSD; 36.3% fat), either alone or together, on maternal glucose tolerance and insulin levels in dams during pregnancy (n = 95 females followed over multiple pregnancies [n = 273]). With prolonged WSD feeding, multiple diet switches, and/or increasing age and parity, WSD was associated with increasingly higher insulin levels during glucose tolerance testing, indicative of insulin resistance. The results suggest that prolonged or recurrent calorically dense WSD and/or increased parity, rather than obesity per se, drive excess insulin resistance and metabolic dysfunction.
