Abstract

Banana bunchy top virus (BBTV) (Nanoviridae: Babuvirus) is transmitted by aphids of the genus Pentalonia in a circulative manner. The cellular mechanisms by which BBTV translocates from the anterior midgut to the salivary gland epithelial tissues are not understood. Here, we used multiple fluorescent markers to study the distribution and the cellular localization of early and late endosomes, macropinosomes, lysosomes, microtubules, actin filaments, and lipid raft subdomains in the gut and principal salivary glands of Pentalonia nigronervosa. We applied colabeling assays, to colocalize BBTV viral particles with these cellular compartments and structures. Our results suggest that multiple potential cellular processes, including clathrin- and caveolae-mediated endocytosis and lipid rafts, may not be involved in BBTV internalization.

Caveolins & Signal Transduction

Caveolins are small proteins with a hairpin loop conformation that are located in the plasma membrane of various cell types where they bind cholesterol and interact with receptors essential for several signal transduction pathways. Here is the latest research.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
