CD4+ T cells, or helper T cells, are one type of lymphocyte that helps coordinate the immune response against infection and disease. They interact and activate other cells in the immune system. The ...

New research has revealed a previously unknown process through which pathogens are able to defeat a cell's defense mechanisms with physical force. The discovery represents a potential game-changer in ...

For years scientists have puzzled over why the intracellular pathogen Salmonella is able to survive — and thrive — in human and animal tissues, even within otherwise hostile cells that are part of the ...

Using the parasite Toxoplasma as our representative pathogen, our work shows that some intracellular pathogens can apply physical forces during their entry into host cells, which then allow the ...

The pathogen Burkholderia thailandensis (purple) uses cellular components (yellow) to form membrane protrusions from one host cell to another (green). Some pathogens hide inside human cells to enhance ...

BLOOMINGTON, Ind. — Similar to a burglar breaking a window to get into a house, Indiana University researchers have discovered a previously unknown process by which pathogens enter a cell with ...
