Summary Introduction

Introduction:

Arboviruses (arthropod-borne viruses) cause an epidemic form of viral encephalitis. These viruses are enveloped and have a single-stranded RNA (ribonucleic acid). The biological vectors responsible for their transmission include insects, mites, and mostly by mosquitoes. Pathogenesis occurs as soon as the mosquito bites, which is followed by the viral replication at that site and in the lymph nodes. During severe cases of viremia, they invade the brain tissue by disrupting the blood–brain barrier resulting in symptoms such as facial paralysis and emotional instability.

Students have asked these similar questions
If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage? Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure? Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?
Using quail and chick embryos, quail-specific antibody and fluorescent tissue-specific antibodies, design an experiment where you investigate the tissues the cranial neural crest can give rise to.  What are four derivatives of the cranial neural crest that you expect to see in the resulting chimeric embryos?
Does the neural crest have to undergo epithelial to mesenchymal transition prior to migration through the developing embryo?  Does the neural crest differentiate into different cell types based on their axial position along the anterior and posterior axis?
