Scientists at Washington University School of Medicine have identified a protective mechanism in Streptococcus pyogenes that could be exploited to create new antibiotics. The discovery reveals how the antitoxin blocks the toxin's activity, sparing the bacteria from self-destruction.
Researchers have identified 39 interaction partners of bacterial toxins, revealing how these toxins manipulate human host cell signaling pathways. This breakthrough could lead to the development of new treatments targeting the underlying mechanisms disrupted by bacterial toxins.
Researchers found that the Bt toxin loses its potency against certain moth and butterfly species unless the insects have specific gut bacteria present. The study suggests that these beneficial bacteria can make the toxin lethal to the insects, highlighting the importance of their presence in pest management.
Biologists at UCSD have discovered a natural defense mechanism in animal cells to ward off certain types of bacteria that secrete toxins. The discovery could lead to the development of new treatments for bacterial diseases such as pneumonia and strep throat.
A University of Toronto study has shown that botox injections can effectively relieve headache pain, especially for patients with neck-related headaches. The treatment group experienced a substantial reduction in pain and improvement in range of motion after just four weeks.
Scientists have identified a new family of insecticidal toxins produced by Photorhabdus luminescens, which are active against a wide range of insects and at least as potent as Bt. The discovery holds promise for the future of natural pest control, particularly in the face of increasing resistance to Bt.
Scientists have discovered a new bacterium, Photorhabdus luminescens, with a toxin effective against a broad range of insect pests. The bacteria can be used as a spray or fed directly to insects, and its genetic material has been licensed for use in crop plants.
A new vehicle has been found to carry therapeutic proteins into living cells, overcoming a major hurdle in the delivery of protein-based drugs. The discovery uses small peptides to substitute for bulky components of bacterial toxins and deliver therapeutic proteins into cells.
