Non-Psychoactive Cannabinoid Reduces Incidence Of Diabetes, Study Says
1. May 18, 2006 - Jerusalem, Israel
Jerusalem, Israel: Administration of the non-psychoactive cannabinoid
cannabidiol (CBD) lowers incidence of diabetes in animals and may one day play a
role in the prevention of human type 1 diabetes, according to preclinical
findings published in the March issue of the journal Autoimmunity.
Researchers at Hadassah University Hospital in Jerusalem reported that
injections of 5 mg per day of CBD significantly reduced the prevalence of
diabetes in mice from an incidence of 86 percent in non-treated controls to an
incidence of only 30 percent. In a separate experiment, investigators reported
that control mice all developed diabetes at a median of 17 weeks (range 15-20
weeks) while a majority (60 percent) of CBD-treated mice remained diabetes-free
at 26 weeks.
Investigators also reported that CBD significantly lowered plasma levels of the
pro-inflammatory cykotines (proteins), INF-gamma and TNF-alpha, and
significantly reduced the severity of insulitis (an infiltration of white blood
cells resulting in swelling) compared to non-treated controls.
"Our results indicate that CBD can inhibit and delay destructive insulitis and
inflammatory ... cykotine production in ... mice resulting in decreased
incidence of diabetes," authors concluded.
Preclinical trial data published earlier this year found that CBD prevents
diabetic retinopathy in animals. The condition, which is characterized by
retinal oxygen deprivation, is the leading cause of blindness in working-age
adults.
Cannabinoids have also been demonstrated to alleviate certain types of
neuropathic pain associated with diabetes, and to reduce glucose levels in
animal models of the disease.
