Class A scavenger receptors mediate extracellular dsRNA sensing, leading to downstream antiviral gene expression in a novel American toad cell line, BufoTad.

Viral double-stranded (ds)RNA is a potent pathogen-associated molecular pattern (PAMP), capable of inducing a strong antiviral state within the cell, protecting the cell from virus infection. In mammals and fish, sensing extracellular dsRNA is mediated by cell-surface class A scavenger receptors (SR-As). Currently, very little is known about SR-As in amphibians, including: sequence, expression patterns and function.

Assessing off-target cytotoxicity of the field lampricide 3-trifluoromethyl-4-nitrophenol using novel lake sturgeon cell lines.

Lampricides are currently being applied to streams and rivers to control the population of sea lamprey, an invasive species, in the Great Lakes. The most commonly used lampricide agent used in the field is 3-trifluoromethyl-4-nitrophenol (TFM), which targets larval sea lamprey in lamprey-infested rivers and streams. The specificity of TFM is due to the relative inability of sea lamprey to detoxify the agent relative to non-target fishes.
