Antigen-presenting cells work to present peptides derived from exogenous and endogenous antigens to circulating T cells, sparking off an immune response. Dendritic cells are unique amongst antigen ...

Most cells in the body send out little messengers called extracellular vesicles that carry proteins, lipids, and other ...

1). What are small molecules? We know best what they are not—nature's DNA, RNA and protein macromolecules residing within their cellular contexts. Cells make naturally occurring small molecules ...

New findings show that the mitochondria powering our cells also control the ability of a DNA repair protein to suppress the senescence-associated secretory phenotype (SASP), which causes zombie-like ...

The study is published in Nature. The authors used a combination of spatial transcriptomics and multiplexed single-cell technologies to pinpoint a B cell subtype in normal intestinal lymphoid ...

there will be equal movement of water molecules in both directions. The solution is said to be in equilibrium – there is therefore no net movement in one direction. Water leaves the cell by osmosis.

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

In humans and other multicellular organisms, cells multiply. This defining feature allows embryos to grow into adulthood, and enables the healing of the many bumps, bruises and scrapes along the way.

An innovative new technique uses a novel DNA barcode system to track hundreds of RNA and protein molecules in single cells within thick biological samples, providing researchers with a full picture of ...

Scientists at YOKOHAMA National University, in collaboration with RIKEN and other institutions in Japan and Korea, have made ...
