Lymph is clear or white fluid that travels through vessels, moves within tissues and work to keep all the parts of the body clean. After passing through the channels of the lymphatic system they drain into the lymph nodes. The lymph nodes act as filters along the lymphatic system. These nodes trap germs like bacteria, viruses, toxins as well as cancer cells and ensure that these are removed from the body.
Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences have developed macrophage–tumor chimeric exosomes that co-activate the immune response and tumor microenvironment to support cancer immunotherapy.
Immunotherapy is an advancing field but there is limited knowledge on the immunity to metastatic tumors in locations like lymph nodes.
CD8+ T cells, also called “killer” T cells, are the killers of the immune system. Upon being primed, they look for and kill cancerous cells or virus-infected cells.
CD8+ T cells -; known as "killer" T cells -; are the assassins of the immune system. Once they are primed, they seek out and destroy other cells that are infected with virus or cells that are cancerous.
Researchers performed a new study and demonstrated that stem-like T cells found in some lymph nodes could exhibit natural cancer-fighting properties.
Lymph nodes are critical to the body's immune response against tumors but paradoxically, cancer cells that spread, or metastasize, to lymph nodes can often avoid being eliminated by immune cells.
Treatment with an immunotherapy drug following kidney cancer surgery, prolonged disease-free survival rates in patients at high risk for recurrence, according to an interim report of a phase 3 clinical trial of adjuvant immunotherapy in this patient population.
After an infection of the human body with a pathogen, a cascade of reactions will usually be set into motion.
A new study has revealed how immune cells migrate to the lymph nodes and help attack harmful viruses and bacteria.
