The blocking of the leptin hormone which is mostly produced in fats cells has a good effect with regard to multiple sclerosis (MS), according to Italian researchers. Giuseppe Matarese and colleagues from Università di Napoli "Federico II" suggest that leptin neutralization may be a possible way to both prevent and treat MS.
Leptin is known to play a critical role in the regulation of food intake, metabolism, and the immune response. Since it had been previously shown that leptin is expressed in active inflammatory lesions of the central nervous system during EAE and MS, Matarese and colleagues investigated the effects of leptin blockade on the induction and progression of EAE in mice.
AdvertisementThey found that leptin blockade in mice, by the use of either anti-leptin antibodies or a form of the leptin receptor unable to bind leptin, either before or after disease onset improved clinical symptoms of disease, slowed disease progression, reduced disease relapses, and reduced the number of antigen-specific T cells.
The authors delved further to unravel the cellular signaling events underlying these beneficial effects. Taken together, the data provides a basis for the development and testing of novel strategies of leptin-based targeting for the potential treatment of MS.
