Nanoparticles from tattoos circulate inside the body, study finds

The elements that make up the ink in tattoos travel inside the body in micro and nanoparticle forms and reach the lymph nodes, according to a study published in Scientific Reports on 12 September by scientists from Germany ...

What is the function of lymph nodes?

If we imagine our immune system to be a police force for our bodies, then previous work has suggested that the Lymph nodes would be the best candidate structures within the body to act as police stations - the regions in ...

Carbon Nanotubes Boost Cancer-Fighting Cells

(PhysOrg.com) -- Yale University engineers have found that the defects in carbon nanotubes cause T cell antigens to cluster in the blood and stimulate the body's natural immune response. Their findings, which appear as the ...

Cancer-causing virus masters cell's replication, immortality

Viruses are notorious for taking over their host's operations and using them to their own advantage. But few human viruses make themselves quite as cozy as the Epstein-Barr virus, which can be found in an estimated nine out ...

Scientists develop vaccine against cattle disease

(Phys.org) —Malignant catarrhal fever (MCF) is a disease that is almost always fatal in cattle. Cows contract MCF after coming into contact with wildebeest carrying a form of herpes virus known as alcelaphine herpesvirus ...

'Stealth' nanoparticles could improve cancer vaccines

Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver ...

Helper cells aptly named in battle with invading pathogens

By tracking the previously unknown movements of a set of specialized cells, Whitehead Institute scientists are shedding new light on how the immune system mounts a successful defense against hostile, ever-changing invaders.

Nanoparticles Detect and Purge Metastases in Lymph Nodes

Colonoscopy represents one of the great weapons against cancer. In one step, a physician can find precancerous lesions in the colon and then cut them out, an on-the-spot intervention that prevents cancer from developing. ...

Lymph node

A Lymph node (pronounced /ˈlɪmf noʊd/) is an organ consisting of many types of cells, and is a part of the lymphatic system. Lymph nodes are found all through the body, and act as filters or traps for foreign particles. They contain white blood cells that use oxygen to process. Thus they are important in the proper functioning of the immune system.

Lymph nodes also have clinical significance. They become inflamed or enlarged in various conditions, which may range from trivial, such as a throat infection, to life-threatening such as cancers. In the latter, the condition of lymph nodes is so significant that it is used for cancer staging, which decides the treatment to be employed, and for determining the prognosis.

Lymph nodes can also be diagnosed by biopsy whenever they are inflamed. Certain diseases affect lymph nodes with characteristic consistency and location.
