Sentence examples for gut membrane from inspiring English sources

The toxicity in A. kuehniella apparently resulted from a change in the gut membrane environment and consequent disruption of digestive enzyme recycling mechanisms.

Although never described as Cry toxin receptors, glycoside-hydrolases were shown to be associated with lipid rafts in the gut membrane of Aedes larvae [ 25].

For example, if the virus crossing the gut membrane results in a wound, naturally occurring gut microbes will also pass into the haemolymph and trigger an immune reaction.

Indeed, pathogens produce lipopolysaccharide (LPS) and other fungal or bacterial toxins which cause locally produced cytokines with consequent intestinal epithelial inflammation, which increases gut membrane permeability.

Because cadherin proteins may help to maintain integrity of the midgut membrane (Midboe et al. 2003; Carrière et al. 2009b), cadherin mutations may cause fitness costs by increasing permeability of the gut membrane to toxic phytochemicals (Carrière et al. 2004b).

These findings support the notion that antigens associated with or anchored in the gut membrane of blood-feeding nematodes have a limited and phenotypically distinct exposure to the host's immune system during a natural infection.

Thus, by using both display systems described here, selection of Cyt1Aa variants capable to bind to insect gut membranes of certain insect species could select Cyt1Aa toxins with toxicity to certain insect pests.

We believe that depending on the binding target (receptor vs insect gut membranes) and toxicity of the native Cry toxin used for library construction the phage display systems described here could be useful to put in place a panning procedures to select improved toxins.

The vaccine utilizes a mixture of the parasite gut mucosal membrane enzymes including H-gal-GP and H11, involved in digesting a blood meal from the host.

While not strictly required, this protein seems to play an important role in the efficiency of this process by interacting with putative virus receptors localized on the gut apical membrane.

The ability of an entomopathogenic fungus to infect its insect host is thought to depend on the coordinated activity of these virulence molecules together with mechanical pressure of hyphae on the exoskeleton and/or gut peritrophic membrane.
