New, Effective Method can Make Rare Cell Types and Disease Patterns Visible in Tissue

The human body contains more than 30 trillion cells. Until recently, the sheer number of cells in the organism meant that approaches to understanding human diseases and developmental processes based on the analysis of single cells were a futuristic vision.

Two types of immune cells interact to give natural protection from tuberculosis

A new study has uncovered the role of B and T cells in controlling tuberculosis (TB) infections.

UConn Health scientists explain why Shigella bacteria can infect humans but not mice

Shigella bacteria can infect humans but not mice. In the March 29 issue of Nature, a team from UConn Health explains why. Their findings may explain the multifariousness of a key weapon of our immune system.

Metal labeling strategy for single-cell multiplexing with mass cytometry

Recently, a new metal labeling strategy has been suggested by researchers from the Suzhou Institute of Biomedical Engineering and Technology (SIBET) of the Chinese Academy of Sciences (CAS) to boost mass cytometry’s sensitivity and increase the number of MC detection channels.

Revealing the structural basis underpinning the biophysical properties of pili

According to the World Health Organization, enterotoxigenic Escherichia coli (ETEC) bacteria are the most common cause of traveler’s diarrhea and cause the greatest number of known community-acquired cases of childhood diarrhea in the developing world.

Maternal vaginal microbiome does not substantially influence the infant stool microbiome

It has been a longstanding assumption that birth mode and associated exposure of newborns to their mothers' vaginal microbiome during delivery greatly affects the development of babies' gut microbiome.

Previously unknown telomere and cancer connection to the immune system revealed

Johns Hopkins Medicine scientists say their 20-year study of more than 200 people with premature aging syndromes caused by abnormally short telomeres, or shortened repetitive DNA sequences at the ends of chromosomes, may upend long-held scientific dogma and settle conflicting studies about how and whether short telomeres contribute to cancer risk.

Immune cells in human blood produce acetylcholine that regulates blood pressure and inflammation

Acetylcholine regulates blood flow, but the source of blood acetylcholine has been unclear. Now, researchers at Karolinska Institutet have discovered that certain T cells in human blood can produce acetylcholine, which may help regulate blood pressure and inflammation.

Clearance of senescent cells by boosting anti-viral immune response

Aging, or senescent cells, which stop dividing but don't die, can accumulate in the body over the years and fuel chronic inflammation that contributes to conditions such as cancer and degenerative disorders.

Neutrophils can affect the success of immunotherapy in treating cancer, study shows

Cancer immunotherapies that recruit a patient's own immune system to destroy tumors have transformed the treatment of many types of cancer. Yet these therapies do not elicit universally good treatment responses.

Harnessing a natural bacterial system to deliver proteins in mice and human cells

Researchers at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT have harnessed a natural bacterial system to develop a new protein delivery approach that works in human cells and animals.

Study helps understand at the cellular level how physical activity contributes to fitness during aging

Regular exercise can guarantee quality of life and longevity, specialists agree. However, exactly how exercise influences the functioning of muscle cells is poorly understood.

COVID-19 vaccines boost the levels of T cells in immunocompromised hematology patients

Researchers found that, despite being heavily immunocompromised, hematology patients generate strong cellular immune responses against SARS-CoV-2 after vaccination, on par with that of healthy individuals.

FDA-approved compound promotes photoreceptor survival in lab models of inherited retinal ciliopathy

A National Eye Institute-led team has identified a compound already approved by the U.S. Food and Drug Administration that keeps light-sensitive photoreceptors alive in three models of Leber congenital amaurosis type 10 (LCA 10), an inherited retinal ciliopathy disease that often results in severe visual impairment or blindness in early childhood.

SARS-CoV-2 infection hijacks and damages parts of infected cells' vital RNA machinery

Coronavirus disease (COVID-19) hijacks parts of infected cells' vital RNA machinery, thereby blocking important functions in the cells. These damaging changes in the RNA can likely be reversed, potentially leading to new drugs against COVID-19, University of Gothenburg researchers show.

Two subtypes of cells that produce insulin discovered

A team of scientists from the Van Andel Institute and the Max Planck Institute for Immunobiology and Epigenetics uncovered two unique subtypes of insulin-producing beta cells, or ß cells, each having important traits that could potentially be used to better understand and treat Type 1 and Type 2 diabetes.

Artificial cells to serve as the powerhouse of the future

Chloroplasts and mitochondria are responsible for producing energy in nature, which is essential for creating sustainable, artificial cells in the lab. In addition to being “the powerhouses of the cell,” as the adage from middle school biology goes, mitochondria are also one of the most difficult intracellular components to artificially clone.

Using better probiotics to maintain a healthy gut microbiome

Bacteria have thousands of genes and functions that we, the human host, do not have. For instance, bacteria can help us digest fiber, provide support to our immune systems, and absorb important nutrients. But reaping the benefits of "good bacteria" is easier said than done.

Cancer that has spread to areas like the lungs can apply the brakes to a natural pathway that should recruit killer T cells directly to where it has metastasized, scientists report.

Study provides a feasible tool to evaluate vesicular endocytosis of NPC1L1-cargos and cholesterol absorption

Excessive cholesterol absorption from intestinal lumen contributes to the pathogenesis of hypercholesterolemia, which is a well-established risk factor for atherosclerotic cardiovascular disease.
