CB3 peptide against "sugar inflammation" in the brain

Elevated blood glucose levels stimulate inflammation in the brain, which can result in the death of neurons. By suppressing the molecular signals associated with inflammation in nerve cells, we can prevent their death.

Anti-inflammatory microparticles will help with a heart attack

Negatively charged microparticles of a copolymer of lactic and glycolic acids with a diameter of 500 nm force inflammatory immune cells to commit suicide, so that damage to the heart after a heart attack is reduced by 2 times.
