Immunodeficient R2g2 Mouse Strain Yields Spleens With Unusual Cytoarchitecture And Sympathetic Innervation, Nicholas Mason Britt, Madeleine Kate Miller, Donald B. Hoover Ph.D., John B. Schweitzer M.D.

Appalachian Student Research Forum

The nervous system and immune system contact one another through two-way communication in order to establish and preserve homeostasis. The sympathetic neurotransmitter norepinephrine has an impact on how the immune system responds by affecting regional blood flow and activation of adrenergic receptors on leukocytes. Former studies showed that immune cells are capable of releasing nerve growth factor allowing for the establishment and continuation of sympathetic nerves in targeted tissues. From this gathered information, it was hypothesized that sympathetic nerves would prove to be less frequent in spleens from the immunodeficient R2G2 mouse strain (Envigo) when compared to 129P3/J (129) and …
