Novel platform allowing universal off-the-shelf T and NK cell access shows potential for immunotherapies

Recent advances in immunotherapy for cancer have stimulated a plethora of studies aimed at developing T cells (white blood cells) and Natural Killer (NK) cells (immune cells with enzymes that can kill tumor cells or cells infected with a virus) in-vitro from pluripotent stem cells-;cells that are able to self-renew by dividing and developing into the three primary groups of cells that make up a human body.

Study provides more nuanced insights into RNA modifications by A-to-I editing during brain development

Mount Sinai researchers have cataloged thousands of sites in the brain where RNA is modified throughout the human lifespan in a process known as adenosine-to-inosine (A-to-I) editing, offering important new avenues for understanding the cellular and molecular mechanisms of brain development and how they factor into both health and disease.

Scientists develop human salivary gland organoids to test SARS-CoV-2 infectivity

In a recent study published in the journal Nature Cell Biology, researchers demonstrated the susceptibility of salivary glands to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in vitro using an organoid culture model.

Study identifies genetic variation that influences lithium-induced neural proliferation

Bipolar disorder, a neuropsychiatric condition that includes manic and depressive episodes, affects about 1% of the population and is strongly influenced by genetics.

Study provides insight into cellular and molecular mechanisms involved in COVID-19 delirium

Researchers from King's College London have shown that when brain cells are directly exposed to blood taken from COVID-19 patients with delirium, there is an increase in cell death and a decrease in the generation of new brain cells.

Oxytocin induces epicardial cell proliferation, study finds

The neurohormone oxytocin is well-known for promoting social bonds and generating pleasurable feelings, for example from art, exercise, or sex. But the hormone has many other functions, such as the regulation of lactation and uterine contractions in females, and the regulation of ejaculation, sperm transport, and testosterone production in males.

Love hormone can activate heart repair mechanisms after cardiac injury, study finds

Researchers show for the first time that the neurohormone oxytocin has a previously unsuspected function in both zebrafish and human cell cultures: it stimulates mature cells in the epicardium of the heart to become stem-like cells, which can replace heart cells lost after damage.

The impact of sleep fragmentation on the clonal diversity of immune cells and the genetic aging of the hematopoietic system

A new study shows that sleep does much more, regulating the normal production of blood cells. This finding underlines how essential a healthy sleep routine is for a normal life.

A good night's sleep promotes immunity

In a recent study published in the Journal of Experimental Medicine, researchers in the United States used mice models to understand how sleep fragmentation affects immunological responses and the epigenetic modifications of hematopoietic stem and progenitor cells (HSPCs). They also conducted a sleep restriction trial in humans to determine HPSC programming and hematopoiesis.

Scientists track origins of group 3 and group 4 medulloblastoma to the rhombic lip

Scientists at St. Jude Children's Research Hospital have discovered which cells give rise to certain high-risk groups of medulloblastoma.

New mechanistic insights on the origin of SARS-CoV-2-induced neurological disorders

Researchers explored the effect of SARS-CoV-2 exposure on the brain.

Single amino acid change in TKTL1 protein underlies greater neuron production in modern humans than Neandertals

Researchers from Dresden uncover a greater neuron production in the frontal lobe during brain development in modern humans than Neandertals, due to the change of a single amino acid in the protein TKTL1.

Study establishes link between Piezo1 and intracellular cholesterol levels during neural development

A new University of California, Irvine-led study reveals how mechanical forces and tissue mechanics influence the morphology of the developing brain, and establishes a direct link in neural stem cells between Piezo1, a mechanically-activated ion channel, and intracellular cholesterol levels during neural development.

Single-cell Stereo-seq reveals new insights into axolotl brain regeneration

The axolotl Ambystoma mexicanum is a popular pet due to its unique and cute appearance. Unlike other salamanders undergoing metamorphosis, axolotls (pronounced ACK-suh-LAH-tuhl) never outgrow their larval, juvenile stage, a phenomenon called neoteny.

Combined stem cell and gene therapy shows promise to treat patients with ALS

Cedars-Sinai investigators have developed an investigational therapy using support cells and a protective protein that can be delivered past the blood-brain barrier.

Study reinforces the potential of Huntington’s treatments that target glia cells

Huntington's disease – a hereditary and fatal genetic disorder – has long been considered a neuronal disease due to the permanent loss of medium spiny motor neurons, the death of which over time is responsible for the clinical hallmarks of the disease: involuntary movements, problems with coordination, cognitive decline, depression, and psychosis.

Discovery of a group of latent stem cells could offer a new approach to treat brain and spinal cord injuries

Scientists at the Francis Crick Institute have identified a group of latent stem cells that respond to injury in the central nervous system of mice. If a similar type of cell exists in humans, they could offer a new therapeutic approach to treat brain and spinal cord injuries.

Scientists identify new driver for rare type of liver cancer

Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Hebrew University in Jerusalem have identified in mice the cell of origin of combined liver/biliary duct carcinomas, a rare type of cancer of the liver.

Terminally exhausted T cells may remain competent for transcription, researchers say

During a battle with cancer, T cells can become exhausted and are no longer able to function properly. The early phase of exhaustion can sometimes be reversed with immunotherapy drugs, but once T cells become too exhausted, it had been thought that this state was irreversible. However, new insights from University of Pittsburgh and UPMC researchers suggest that even the most fatigued T cells can be revived.
