Lymph nodes, hundreds of small structures located throughout the body, play a pivotal role in immunity, including anti-tumor immune responses. White blood cells, also known as lymphocytes, reside in ...

A new method to keep human lymph node tissue alive and functioning outside the body for several days could give researchers a much clearer view of how our immune system responds to infections, ...

The assumption that lymph nodes necessarily underlie immunity stems from experiments with mutant mice that lack lymph nodes, known as Alymphoplasia (aly/aly) mutants. These mice fail to display proper ...

A team of researchers, led by the Peter Doherty Institute for Infection and Immunity (Doherty Institute), explored the cellular and molecular interactions revealing how lymph nodes play a crucial role ...

Lymph nodes trigger very different immune responses – depending on which body tissue they are connected to. Special T cells are responsible for this newly discovered relation. The human body contains ...

Stanford University-led researchers report that tumor cells hijack mitochondria from immune cells, reducing anti-tumor immune ...

Immunofluorescence of a lymph node metastasis: CD11B-positive myeloid cells (green), pan-cytokeratin-positive breast cancer cells (red) and collagen I from fibroblastic reticulum cells (blue). 500 µm, ...
