The well-established existence of sex differences in immune responses, including immune responses driven by T cells, cuts both ways. Females tend to have a stronger immune response to pathogens, yet ...

Sterols, such as cholesterol in our bodies or ergosterol in yeast cells, are among the most abundant lipids in eukaryotic cells, yet are synthesized through notoriously long, complex metabolic ...

Researchers have produced the most detailed map yet of how stem cells in the growing tip of a plant begin their journey to form the many cell types that shape flowers and stems. They identified 18 ...

Initially, cells are dissociated from liver tissues into single-cell suspensions using in vivo enzymatic perfusion or ex vivo digestion methods. The cells of interest are then enriched from the ...

Dendritic cells (DCs) are among the first immune sentinels to detect viruses, bacteria, or other challenges. These specialized messengers alert T cells while orchestrating either a measured calm or a ...

New scientific methods could one day render animal studies—the standard in research laboratories for more than 100 years—obsolete. Clive Svendsen, Ph.D., executive director of the Board of Governors ...

Researchers at the University of Houston are pushing the boundaries of biomedical innovation with a discovery that could transform treatment for one of cancer's most devastating complications. In a ...

Apoptosis is a process in which cells die off, intentionally. This programmed cell death pathway helps eliminate billions of cells every day, most of which are blood or gut cells, so they can be ...

Full-body defense does not always look the way textbooks say it should. In planarian flatworms, a newly identified cell type ...
