This can then lead to exocrine pancreatic insufficiency. Lupus. The autoimmune disease lupus can cause a rare condition called autoimmune pancreatitis, where the bodyâs T-cells (blood cells that fight infection) attack the pancreas. Autoimmune pancreatitis can lead to chronic pancreatitis and, in some cases, to exocrine pancreatic insufficiency,â Gress says.
Quick Answer. When a neuron is stimulated by another neuron, an ionic gradient is created across the neuron's plasma membrane, which creates an electric current flow in the neuron. The current flow travels down the axon and causes neurotransmitters to be released at the terminals to stimulate downstream neurons. Continue Reading
The neuron that is acted upon by the chemical is termed the postsynaptic neuron. The neurotransmitter molecules released from the presynaptic vesicles traverse the synaptic gap and bind to proteins, termed neurotransmitter receptors, on the surface membrane of the postsynaptic neuron.ABA B receptors also are found on presynaptic terminals of neurons in many brain regions (Bowery et al. 1990). When activated, these receptors inhibit neurotransmitter release via mechanisms that involve inhibition of voltage-gated calcium channels whose function is necessary for proper release.
