I'm not gonna lie.. a fair bit of this article goes way over my head, but what I have managed to gather is that through research like this we could
learn how to control the human immune system?
Which in turn means that we could stop AIDS from being deadly?..
I may have jumped to the wrong conclusion.. someone please correct me. I am pretty sleep deprived.

CD4 lymphocytes: CD4 (cluster of differentiation 4) is a glycoprotein expressed on the surface of T helper cells, monocytes, macrophages, and
CD4 is a part of the immunoglobulin superfamily.
immunoglobulin superfamily: The immunoglobulin superfamily (IgSF) is a large group of cell surface and soluble proteins that are involved in the
recognition, binding, or adhesion processes of cells. Molecules are categorized as members of this superfamily based on shared structural features
with immunoglobulins (also known as antibodies); they all possess a domain known as an immunoglobulin domain or fold.
Vagus Nerve: The vagus nerve (play /ˈveɪɡəs/ US dict: vā′·gəs), also called pneumogastric nerve or cranial nerve X, is the tenth of twelve
(excluding CN0) paired cranial nerves. Upon leaving the medulla between the medullary pyramid and the inferior cerebellar peduncle, it extends through
the jugular foramen, then passing into the carotid sheath between the internal carotid artery and the internal jugular vein down below the head, to
the neck, chest and abdomen, where it contributes to the innervation of the viscera. Besides output to the various organs in the body, the vagus nerve
conveys sensory information about the state of the body's organs to the central nervous system.
Norepinephrine is released when a host of physiological changes are activated by a stressful event.
In the brain, this is caused in part by activation of an area of the brain stem called the locus ceruleus. This nucleus is the origin of most
norepinephrine pathways in the brain. Noradrenergic neurons project bilaterally (send signals to both sides of the brain) from the locus ceruleus
along distinct pathways to many locations, including the cerebral cortex, limbic system, and the spinal cord, forming a neurotransmitter system.
Norepinephrine is also released from postganglionic neurons of the sympathetic nervous system, to transmit the fight-or-flight response in each
tissue, respectively. The adrenal medulla can also be counted to such postganglionic nerve cells, although they release norepinephrine into the
I'm not going to pretend to know enough to speak intelligently about the topic, but from my humble ignorant understanding... I'd say you are fairly
accurate in your description.
If anybody can shed some light on this subject, that would be great! I'm going to shoot my buddy an email, who went to college for this fun stuff,
and see what he say has to say... if there's anything worth mentioning from his response... I will be back to post it!
