Antidepressants can help delay ageing of brain cells, says this study

Administering commonly used antidepressant fluoxetine to mice helped restore youthful flexibility to their ageing brain cells, showed a study. The study provides fresh evidence that the decline in the capacity of brain cells to change, called “plasticity,” rather than a decline in total cell numbers may underlie some of the sensory and cognitive declines associated with normal brain ageing.

Cancer cells override body clock to survive conditions that kill normal cells

For tumours to grow and spread, cancer cells must make larger than normal amounts of nucleic acids and protein, so they can replicate themselves. Yet in both normal and cancer cells that increase their synthesis of protein, a small percent of those proteins do not fold properly. When that happens, the cell activates its unfolded protein response (UPR), which slows ... Read More »

Insufficient zinc supply to lung cells can cause respiratory diseases

Respiratory diseases that develop due to an overproduction of mucus are caused by an insufficient zinc supply to lung epithelial cells, a study has found. Obstructive pulmonary disease is a collective term for refractory respiratory diseases with chronic airway inflammation and excessive mucus retention that are accompanied by airway obstruction. They include chronic obstructive pulmonary disease (COPD) that presents with ... Read More »

Scientists develop drug that re-programmes cells to fight cancer

Australian researchers have developed a drug capable of reprogramming the immune system to fight cancer, it was announced on Thursday. The landmark new therapy, developed by the Peter MacCallum Cancer Centre, involves removing immune cells from the body to genetically enhance them before putting them back in the body to fight cancer, Xinhua reports. The form of immunotherapy has previously ... Read More »
