Study clarifies the impact of getting old on hematopoietic stem cells Kumar Jeetendra | December 25, 2020 By shifting mouse elderly hematopoietic stem cells (aged HSCs) to the environment of young mice (bone marrow niche), it was shown that the pattern of stem cell gene expression was rejuvenated to that of young hematopoietic stem cells. On the other hand, the function of elderly HSCs failed to recover in the young bone marrow …
New UCLA-formed gadget moves mitochondria into at least 100,000 or more beneficiary cells Kumar Jeetendra | January 1, 2021 Scientists from the UCLA Jonsson Comprehensive Cancer Center have developed a simple, high-throughput way of transferring isolated mitochondria and their associated mitochondrial DNA into mammalian cells. This approach enables researchers to tailor a key genetic component of cells, to study and potentially treat debilitating diseases such as cancer, diabetes and metabolic disorders. A study, published …
Putatively juvenile dendritic cells may actuate hearty resistant reactions in young children Kumar Jeetendra | January 20, 2021 A study by Ludwig-Maximilians-Universitaet (LMU) in Munich researchers demonstrates that putatively immature dendritic cells found in young children are able to induce strong immune responses. Dendritic cells are a vital component of the innate immune system, which represents the body’s first line of defense against infectious agents and tumor cells. Their job is to trigger …
UNSW builds up a clay based ink to 3D-print bone parts with living cells Kumar Jeetendra | January 26, 2021 3D printers may one day become a permanent fixture of the operating theatre after UNSW scientists showed they could print bone-like structures comprising living cells. Researchers from UNSW Sydney have developed a ceramic-based ink which may allow surgeons in the long run to 3D-print bone elements complete with living cells which could be used to …
Researchers develop experimental direct-acting antiviral treatment to treat COVID-19 Kumar Jeetendra | May 18, 2021 An international team of scientists from the Menzies Health Institute Queensland (MHIQ) at Griffith University and from City of Hope, a research and treatment center for cancer, diabetes and other life-threatening diseases in the U.S., have developed an experimental direct-acting antiviral therapy to treat COVID-19. Conventional antivirals reduce symptoms and help people recover earlier. Examples …
Mild cases of COVID-19 give enduring antibody, shows study Kumar Jeetendra | May 24, 2021 Months after recovering from mild cases of COVID-19, people still possess immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine in St. Louis. Such cells could persist for a lifetime, churning out antibodies all of the while. The …
