Researchers at the University of Illinois have isolated and characterized an insulin gene from the marine mollusk Aplysia californica. The study reveals a unique peptide, the 'D' peptide, which is separated from the standard two-chain insulin structure by a 'C' peptide.
Researchers have developed a new family of chemicals that bind specifically to the gp41 pocket, halting HIV's ability to infect cells. The compounds, created using mirror-image phage display, show promise as potential oral treatments for HIV, with advantages including reduced cell membrane penetration and lower likelihood of resistance.
Scientists used peptide injections to divert the immune system and prevent disease progression in mice with type-I diabetes. The study suggests peptide-based immunotherapy may be effective for people at risk of developing the autoimmune disease.
Researchers found that a small peptide, IM862, showed significant anti-angiogenesis activity in a human clinical trial, resulting in major responses in 37% of patients. The peptide inhibits blood vessel formation and modulates the immune system, offering a potential treatment for Kaposi's Sarcoma with improved safety profiles.
Northwestern University researchers have identified key peptides that can halt and even reverse kidney disease in lupus. The peptides were found to be effective in delaying the onset of severe kidney disease in young mice and prolonging survival in adult mice with established kidney disease.
Researchers discover the structure of a key compound enabling the bacterium's deadly mechanism and create molecules that block its effects in mice. The study provides a novel way to combat Staphylococcus aureus infections without killing the bacteria, potentially addressing antibiotic resistance.
A Purdue University study shows that proteins can replicate themselves and adapt to changes, expanding the scientific view of how life began. The study also found that changes to the environment affect the types of peptides that can be formed.
Scientists have identified peptides substance P and neurokinin A as key components in the body's pain responses. The study suggests that these peptides work together to produce moderate-to-severe pain, offering a potential target for new pain treatments.
Researchers have developed molecular sensors that can detect specific proteins in blood plasma or other biological fluids with high accuracy. The sensors could also be used to construct an environmental detector, giving new insights into cell functioning and promoting medical diagnostics.
Researchers discovered a molecule, ERAB, that causes early neuron damage in Alzheimer's disease. The finding may lead to therapies that inhibit the interaction of ERAB and amyloid-B peptide, protecting neurons from damage.
Researchers at Johns Hopkins Medicine discovered a peptide that closes an NMDA glutamate receptor, potentially aiding the development of stroke treatment drugs. The peptide, known as Mag-1.5, can help regulate communication between nerve cells and may provide insights for potential new therapies.
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.
