Researchers have produced the most detailed map yet of how stem cells in the growing tip of a plant begin their journey to ...

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 ...

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 ...

Scientists at the University of Western Australia and the Perron Institute for Neurological and Translational Science have made a breakthrough in understanding how cells in our body respond to ...

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 ...

A Yale-led study uncovered unexpected communication between retinal visual pathways that were thought to operate separately.

Researchers at ETH Zurich have identified a compound that blocks the aggregation of GRK2, a kinase protein whose clumping inside neurons drives mitochondrial damage and accelerates cell death in ...

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