Living organisms experience various stresses during their lifespans. These stresses include radiation, ultraviolet rays, and chemical substances which directly damage DNA and cause cancer. Organisms are able to speedily repair … Continue Reading Study identifies genes which control cellular senescence.
Leukemia, or blood cancer, involves pathological alterations in the body’s hematopoietic system. In acute myeloid leukemia, it is specifically the bone marrow that is affected. In a healthy body, different … Continue Reading Previously unknown cell-death pathway mapped in leukemia cells.
The human immunodeficiency virus (HIV) is a lentivirus which causes HIV infection and over time AIDS. Developing effective prevention measures for HIV is hindered by incomplete knowledge of the phenotype … Continue Reading New technology lights up location of first cells to be infected in female HIV transmission.

It is known that cell death is a mechanism used by multicellular organisms to help them survive by removing infected, damaged or unwanted cells. Mitochondria are known as the energy-generating … Continue Reading Researchers identify previously unknown pathway for cell death.
Children who received general anesthesia for surgery before age 4 had diminished language comprehension, lower IQ and decreased gray matter density in posterior regions of their brain, according to a … Continue Reading Researchers link surgical anesthesia in young children to adverse effects on IQ, brain structure.
Scientists from the CNRS, INSERM and Université de Limoges have demonstrated that the production of type E immunoglobulins (IgE)2 by B lymphocytes induces a loss in their mobility and the … Continue Reading Researchers map programmed cell death in immune cells to prevent allergy.
Walter and Eliza Hall Institute researchers have for the first time revealed how dying cells are hidden from the immune ‘police’ that patrol the body. The research answers a decades-old … Continue Reading Decades-old mystery about the death of cells uncovered by scientists.
Scientists at Trinity College have made an important breakthrough in the medical community’s understanding of Parkin, a protein that regulates the repair and replacement of nerve cells within the brain. … Continue Reading Scientists make breakthrough in understanding Parkinson’s disease.
Researchers at the UNC School of Medicine have discovered that the protein PARC/CUL9 helps neurons and brain cancer cells override the biochemical mechanisms that lead to cell death in most … Continue Reading Neurons, brain cancer cells require the same little-known protein for long-term survival.
