Medicinal cannabis extracts are neuroprotective against Aβ(1-42)-mediated toxicity in vitro.

Phytocannabinoids inhibit the aggregation and neurotoxicity of the neurotoxic Alzheimer's disease protein β amyloid (Aβ). We characterised the capacity of five proprietary medical cannabis extracts, heated and non-heated, with varying ratios of cannabidiol and Δ9-tetrahydrocannabinol and their parent carboxylated compounds to protect against lipid peroxidation and Aβ-evoked neurotoxicity in PC12 cells. Neuroprotection against lipid peroxidation and Aβ1-42-induced cytotoxicity was assessed using the thiazolyl blue tetrazolium bromide (MTT) assay. Transmission electron microscopy was used to visualise phytocannabinoid effects on Aβ1-42 aggregation and fluorescence microscopy. Tetrahydrocannabinol (THC)/tetrahydrocannabinolic acid (THCA)-predominant cannabis extracts demonstrated the most significant overall neuroprotection against Aβ1-42-induced loss of PC12 cell viability. These protective effects were still significant after heating of extracts, while none of the extracts provided significant neuroprotection to lipid peroxidation via tbhp exposure. Modest inhibition of Aβ1-42 aggregation was demonstrated only with the non-heated BC-401 cannabis extract, but overall, there was no clear correlation between effects on fibrils and conferral of neuroprotection. These findings highlight the variable neuroprotective activity of cannabis extracts containing major phytocannabinoids THC/THCA and cannabidiol (CBD)/cannabidiolic acid (CBDA) on Aβ-evoked neurotoxicity and inhibition of amyloid β aggregation. This may inform the future use of medicinal cannabis formulations in the treatment of Alzheimer's disease and dementia.

Dapagliflozin prevents reproductive damage caused by acute systemic inflammation through antioxidant, anti-inflammatory, and antiapoptotic mechanisms.

Dapagliflozin (DPG) is a sodium-glucose cotransporter-2 (SGLT2) inhibitor that has been suggested to possess anti-inflammatory properties in diabetes. The aim of this study is to evaluate the role of DPG administration in preventing lipopolysaccharide (LPS)-induced damage in the female genital system. Thirty-two female Wistar Albino rats were randomly allocated into four groups: control group, LPS group, LPS + DPG group and DPG group. At the end of the experimental phase, ovary, fallopian tube and uterus tissues were collected for histopathological, immunohistochemical, genetic and biochemical analyses. The findings showed that LPS caused histopathological changes characterized by marked hyperaemia, mild to moderate haemorrhage, oedema and neutrophil leucocyte infiltrations and degenerative and necrotic changes in the female genital tract. In addition, it decreased total antioxidant status (TAS), increased total oxidant status (TOS) and oxidative stress index (OSI) levels. LPS also increased the expressions of Cas-3, G-CSF and IL-1β in the ovary, fallopian tubes and uterus immunohistochemically. While Claudin-1 expression decreased, NLRP3 and AQP4 gene expressions increased due to LPS. However, DPG treatment prevented all these changes. The results of this study indicate that, DPG can be used to prevent LPS-induced lesions in the female reproductive system.
