Exosomes derived from cardiac parasympathetic ganglionic neurons inhibit apoptosis in hyperglycemic cardiomyoblasts.

Diabetic cardiomyopathy is known to involve two forms of cardiac cell death: apoptosis and necrosis. However, it remains unknown whether hyperglycemia-induced apoptosis in the H9c2 cell culture system is inhibited by parasympathetic ganglionic neurons (PGN) derived exosomes (exos). We isolated PGN and sympathetic ganglionic neurons (SGN) from the right stellate ganglion in rats, and derived exos from these sources.

Pathophysiology of autism spectrum disorders: revisiting gastrointestinal involvement and immune imbalance.

Autism spectrum disorders (ASD) comprise a group of neurodevelopmental abnormalities that begin in early childhood and are characterized by impairment of social communication and behavioral problems including restricted interests and repetitive behaviors. Several genes have been implicated in the pathogenesis of ASD, most of them are involved in neuronal synaptogenesis. A number of environmental factors and associated conditions such as gastrointestinal (GI) abnormalities and immune imbalance have been linked to the pathophysiology of ASD.

Central nervous system acting drugs in treatment of migraine headache.

Migraine is a primary headache disorder with an unknown pathophysiology. The growing evidence in recent years indicates migraine being a brain disorder, a sensory dysmodulation, and a system failure of normal sensory processing of the brainstem that involves the vascular tone and pain. At the moment, triptan family and NSAIDs are the first choice drugs for the treatment of acute migraine.

Expression of cholera toxin B-proinsulin fusion protein in lettuce and tobacco chloroplasts--oral administration protects against development of insulitis in non-obese diabetic mice.

Lettuce and tobacco chloroplast transgenic lines expressing the cholera toxin B subunit-human proinsulin (CTB-Pins) fusion protein were generated. CTB-Pins accumulated up to ~16% of total soluble protein (TSP) in tobacco and up to ~2.5% of TSP in lettuce.
