WebOct 29, 2024 · Parvo is an infectious DNA virus that commonly causes severe illness in young and unvaccinated dogs. It primarily affects the body’s rapidly dividing cells, meaning the intestinal tract and bone marrow are the most affected. Heart muscle cells of very young puppies can also be damaged by parvovirus. WebParvocellular neurosecretory cells are small neurons that produce hypothalamic releasing and inhibiting hormones. The cell bodies of these neurons are located in various nuclei of the hypothalamus or in closely related areas of the basal brain, mainly in the medial zone of the hypothalamus.
