Research Summary:

Mechanisms of Toxicity and Membrane Transport

The lab has three principal research areas all utilizing a cellular and molecular approach to elucidate the mechanisms of toxicity and cell membrane transport. The focus of the first area is to elucidate the mode of action of toxins derived from Bacillus thuringiensis and Clostridium bifermantans. The research aims to gain a molecular understanding of the characteristics of these toxins and how they interact with cellular targets, which result in a disruption of ion regulation and lethality. Current research projects include the elucidation of structure and function relationships of these bacterial toxins; toxin receptor isolation and an attempt to define how these receptors modulate in vivo toxicity.

A second research focus is on insect cell membrane transport, and how toxins affect this function. Currently, the laboratory is characterizing ion and amino acid transporters. The lab is focusing on the Na+/H+ exchangers that play a key role in transport of high salt load on mosquitoes following a blood meal. Studies include functional analysis and regulation of these exchangers in the mosquito Malpighian tubules. In conjunction with this effort the lab is also characterizing transport processes involved in nutrient uptake following a blood meal, and the regulation of such transport.

Finally, the lab has a long ongoing interest in xenobiotic metabolism and characterization of the effects of environmental toxicants on mammalian systems. This molecular toxicology emphasis defines how toxicants regulate the expression of the soluble epoxide hydrolase and fatty acid metabolism.
