Researchers reveal surprising propulsion system used by stem cells

Researchers have discovered the surprising propulsion system that enables these regenerative cells to migrate through surrounding tissue to repair the damage.

New discovery helps explain how COVID-19 suppresses the body’s immune response

Seeking to understand why COVID-19 is able to suppress the body's immune response, new research from the USC Leonard Davis School of Gerontology suggests that mitochondria are one of the first lines of defense against COVID-19 and identifies key differences in how SARS-CoV-2, the virus that causes COVID-19, interacts with mitochondrial genes when compared to other viruses.

Two cryo-EM studies identify different types of ATP synthase organization

The mitochondrial ATP synthase is energy-converting macromolecular machine that uses the electrochemical potential across the bioenergetic membrane called cristae. This potential is maintained via a membrane curvature that is induced by ATP synthase assembled in dimers.

Researchers discover new way to control natural killer cells in immune system

UC San Francisco scientists have discovered a new way to control the immune system's "natural killer" (NK) cells, a finding with implications for novel cell therapies and tissue implants that can evade immune rejection.

Proteogenomic study may lead to more effective treatments for head and neck squamous cell carcinoma

Proteogenomic studies may provide a better understanding of how to match cancer patients with an effective treatment for their specific cancer.

New class of protein materials can influence cell signaling

A new study has revealed that a novel class of protein material that communicates with living cells without being absorbed by them can affect cell signaling. The protein material does this by attaching and sequestering cell surface receptors.

Researchers create molecular ON-OFF switches to regulate CAR T cell activity

CAR T cells are a breakthrough class of effective but often toxic cancer therapies. To prevent overactivation, switchable CAR T cells were engineered that can be turned on and off with an approved, widely used cancer drug.

Study addresses mystery of how chromosomes are inherited during cell division

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within this intricate process is the transfer of DNA through each subsequent cell split within discrete packets called chromosomes.

DNA-editing technique used to extend lifespan of mice with progeria

Researchers have successfully used a DNA-editing technique to extend the lifespan of mice with the genetic variation associated with progeria, a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy.

Microbe found in the colon may promote breast cancers

A microbe found in the colon and commonly associated with the development of colitis and colon cancer also may play a role in the development of some breast cancers, according to new research from investigators with the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy.

Scientists modify toxic pesticide to treat antibiotic-resistant bacteria

A significant class of heterocyclic compounds, called N-Aryl-C-nitroazoles, is used as fungicides and pesticides. But these substances could be harmful to human beings and cause mutations.

Study identifies the effects of nutritional deficiency on patient survival after cardiac surgery

Nutrients are the structural components of food that the body needs to function properly. They are divided into macronutrients (proteins, fats, carbohydrates) and micronutrients (vitamins, provitamins, various minerals, and so on). Their shortage is called nutritional deficiency.
