Study: CBD Reduces Inflammation in Canine Mammary Cancer Cells
Researchers from the University of Messina found that cannabidiol (CBD) reduced inflammation in canine mammary carcinoma cells without harming cell viability, suggesting it may have therapeutic potential for one of the most common cancers affecting female dogs. The study was conducted by researchers from the Department of Veterinary Science and the Department of Chemical, Biological, …
Study: CBD Triggers Anti-Cancer Effects in Breast Cancer Cells, Including Drug-Resistant Line
A new study published in Pharmaceuticals found that cannabidiol (CBD) reduced breast cancer cell growth, promoted apoptosis and altered the expression of genes tied to several major cancer pathways. Researchers from Recep Tayyip Erdogan University and Yozgat Bozok University examined the effects of CBD on two breast cancer cell lines: MCF-7, which is sensitive to …
Study: THC and CBD May Strengthen Cisplatin’s Effects Against Cervical Cancer Cells
According to a new study published by Cancer Reports, combining cisplatin with delta-9 tetrahydrocannabinol (THC) and cannabidiol (CBD) enhanced the chemotherapy drug’s anticancer effects in cervical cancer cells. Researchers from the University of Pretoria examined how THC and CBD interacted with cisplatin, a commonly used chemotherapy drug for cervical cancer that can be limited by …
Study Finds CBD May Strengthen Effects of Breast Cancer Drug
A new study published by Molecular and Cellular Biochemistry found that cannabidiol (CBD) may enhance the effects of the cancer drug olaparib in certain breast cancer models, particularly triple-negative breast cancer. Researchers from Yeditepe University examined whether CBD could improve the response of BRCA-wild type breast cancer cells to olaparib, a PARP inhibitor commonly used …
Study: CBD Shows Benefit for Schizophrenia Symptoms
Cannabidiol (CBD) may provide a small but statistically significant benefit for certain schizophrenia symptoms when used alongside standard antipsychotic treatment, according to a new systematic review and meta-analysis. The study, published in European Archives of Psychiatry and Clinical Neuroscience, was conducted by researchers from the University of Thessaly, the Technical University of Munich and the …
Study: CBD Reduces Heroin-Seeking Behavior by Reversing Brain Changes Linked to Relapse
A new study published in Biological Psychiatry found that cannabidiol (CBD) reduced heroin-seeking behavior by reversing brain changes linked to relapse, particularly in pathways tied to microglial function. The study was conducted by researchers from the Icahn School of Medicine at Mount Sinai. Researchers examined how CBD affects the basolateral amygdala, or BLA, a brain …
Study: CB1 Receptors Found Critical for Myelin Regeneration and Brain Repair
A new study published in Cell Communication and Signaling finds that CB1 cannabinoid receptors play a crucial role in the final stages of brain cell development needed for myelin repair, offering new insight into how the body’s endocannabinoid system influences recovery from neurological damage. Researchers from Complutense University and the Instituto Universitario de Investigación en …
