It is generally agreed that a number of types of nutritional deficiencies, including vitamin D-deficient rickets, can cause a temporary state of immune deficiency. As a result, children with rickets ...

Much like humans generate mountains of garbage, our cells are constantly discarding proteins that are damaged or no longer needed. The cellular waste disposal system called the proteasome is best ...

Gut bacteria aren’t just passive passengers—they can actively send proteins straight into our cells. Using microscopic injection systems, even harmless microbes can influence immune responses and ...

Hai-Hui "Howard" Xue, Ph.D., of the Hackensack Meridian Center for Discovery and Innovation (CDI) have shown how a critical pathway is fundamental to the immune system, in a new papers in the journal ...

T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on ...

A T-cell response, or cellular immunity, was present in 100 people six months after their initial COVID-19 infection, according to a study published in the preprint server BioRxiv. Researchers from ...

New research comparing four different flu vaccines found that the ability of the vaccines to activate cells of the immune system that help to protect against infection varied greatly depending on the ...

Detailed immune profiling in long-term care populations reveals that SARS-CoV-2 vaccines and infections drive powerful virus-specific responses while leaving lifelong common cold immunity largely ...

New research comparing four different flu vaccines found that the ability of the vaccines to activate cells of the immune system that help to protect against infection varied greatly depending on the ...

Rooted in place, plants have little ability to flee dangerous situations. Additionally, their lack of a dedicated immune system means that, to combat an infection, every cell needs to be able to mount ...
