The most poisonous substance on Earth – already used medically in small doses to treat certain nerve disorders and facial wrinkles – could be re-engineered for an expanded role in helping millions of people with rheumatoid arthritis, asthma, psoriasis and other diseases, scientists are reporting. Their study appears in ACS' journal Biochemistry. Edwin Chapman and colleagues explain that toxins, or poisons, produced by Clostridium botulinum bacteria, cause of a rare but severe...

A slight change in molecular structure introduced by genetic engineering gives crop-protecting proteins called Bt toxins a new edge in overcoming resistance of certain pests, a UA-led team of researchers reports in Nature Biotechnology One of the most successful strategies in pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat them. But insect pests are evolving resistance...

(Ivanhoe Newswire) -- Spider venom could hold the key to understanding how the body operates. Researchers have discovered a toxin from the American Funnel Web spider acts on T-type and N-type calcium channels. They say the toxin offers a new target for studying T-type channels, which play a role in congestive heart failure, hypertension, epilepsy and pain. The investigators, from the University of California at Riverside, purified the toxin and created a recombinant version. "If we can...

Discovery by California researchers described today at Biophysical Meeting in Baltimore Spider venom toxins are useful tools for exploring how ion channels operate in the body. These channels control the flow of ions across cell membranes, and are key components in a wide variety of biological processes and human diseases. A newly identified toxin from the American Funnel Web spider acts on T-type and N-type calcium channels, researchers from the University of California at Riverside have...

Bacteria often attack with toxins designed to hijack or even kill host cells. To avoid self-destruction, bacteria have ways of protecting themselves from their own toxins. Now, researchers at Washington University School of Medicine in St. Louis have described one of these protective mechanisms, potentially paving the way for new classes of antibiotics that cause the bacteria's toxins to turn on themselves. Scientists determined the structures of a toxin and its antitoxin in Streptococcus...

Red tides and similar blooms can render some seafood unsafe to eat, though it can be difficult to tell whether a particular batch harbors toxins that cause food poisoning.A new kind of marker developed by chemists at the University of California, San Diego, and reported in the journal ChemComm makes it easier to see if shellfish are filled with toxin-producing organisms.Mussels and oysters accumulate single-celled marine creatures called dinoflagellates in their digestive systems as they...

In a breakthrough, UCI chemists create synthetic antibodies that block bee venom UC Irvine researchers have developed the first "plastic antibodies" successfully employed in live organisms "“ stopping the spread of bee venom through the bloodstream of mice. Tiny polymeric particles "“ just 1/50,000th the width of a human hair "“ were designed to match and encase melittin, a peptide in bee venom that causes cells to rupture, releasing their contents. Large quantities of...
