Researchers have found that adult stem cell changes underlie Hutchinson-Gilford Progeria Syndrome (HGPS), a rare genetic disease causing premature aging. The study reveals progerin's effect on adult mesenchymal stem cells, leading to accelerated maturation into bone and loss of fatty tissues.
Researchers developed a multistage delivery system to improve injectable drug efficacy, targeting diseased cells and releasing therapeutics in a controlled manner. The system uses mesoporous silicon particles to circumvent biobarriers and deliver diagnostic agents or therapeutic agents.
Researchers found ski tourism raises stress levels among capercaillie, harming their fitness and ability to breed. The study recommends keeping forests inhabited by the birds free from tourism infrastructure.
A Canadian-US research team has solved a major genetic mystery: how a protein in some people's DNA guards against killer immune diseases like HIV. The discovery of FOX03a offers promise for HIV vaccine development and treatments for other immune diseases, such as cancer and rheumatoid arthritis.
A study by Ohio State University found no improvement in immune status, wound healing, or pain control among participants exposed to aromatherapy oils. However, lemon oil showed a positive effect on moods, while lavender oil had no impact.
Researchers at Rockefeller University discovered a tiny RNA molecule that helps skin cells form a protective barrier. MicroRNA-203 plays a crucial role in regulating genes outside the cell's nucleus, specifically suppressing the activity of p63 to prevent stem cells from proliferating excessively.
Researchers at USC have identified A20 as an antigen presentation attenuator that prevents excessive inflammation of dendritic cells. By inhibiting A20, they found a new way to overcome regulatory T cell-mediated suppression and trigger strong antitumor immunity.
Researchers have identified an additional seven gene regions associated with coeliac disease, revealing a connection to type 1 diabetes. The study also highlights the importance of immune response genes in the development of coeliac disease, providing new insights into its causes and potential treatments.
