One of the greatest challenges faced by cancer surgeons is to know exactly which tissue to remove, or not, while the patient is under anesthesia. A team of surgeons and scientists at University of California, San Diego School of Medicine have developed a new technique that will allow surgeons to identify during surgery which lymph nodes are cancerous so that healthy tissue can be saved. The findings will be published in the January 15 print edition of Cancer Research. "This research is...

Germinal centers are sites in the organs of the lymphatic system, formed during the course of an immune response to infection, where B cells intensely proliferate and modify their DNA in order to produce antibodies specific for the pathogen. However, it is known that the vast majority of lymphomas derive from the B cells at the germinal centers. Now, Dr. Dinis Pedro Calado and Dr. Klaus Rajewsky of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch have identified...

Chronic inflammatory conditions are extremely common diseases in humans and in the entire animal kingdom. Both in autoimmune diseases and pathogen-caused diseases, the inflamed areas are rapidly colonized by antibody producing B lymphocytes — which organize themselves in highly structured areas called "lymphoid follicles". The scaffold of such follicles is provided by follicular dendritic cells (FDCs). FDCs have important roles in the development of immune responses, since they trap...

Researchers probe origin of optimized antibodies against infections An organism's ability to make new antibodies and use them to optimize its own immune defenses is of central importance in the fight against pathogens. In the case of severe infections, the overall relative speed with which an immune response proceeds could mean the difference between life and death. An international team of scientists, among them systems immunologist Prof. Michael Meyer-Hermann of the Helmholtz Centre for...

Contrary to a trend in treatment, breast cancer patients with suspicious lymph nodes should have an ultrasound-guided axillary node biopsy, and if that biopsy is positive these patients should undergo an axillary dissection, a new study shows. The study, conducted at the University of Pittsburgh Medical Center, compared 199 patients with a positive ultrasound-guided axillary node biopsy to 434 patients with a positive sentinel lymph node biopsy. "About 50% of patients with a positive...

Lymph nodes help to fight off infections by producing immune cells and filtering foreign materials from the body, such as bacteria or cancer cells. Thus, one of the first places that cancer cells are found when they leave the primary tumor is in the lymph nodes. The spread of cancer cells to the lymph nodes, lymphatic metastasis, is known to indicate a poor prognosis in many types of cancers; how tumor cells reach the lymph nodes, however, is not well understood. A new study by Dr. Heide...

Photoacoustic tomography can 'see' in color and detail several inches beneath the skin Every new imaging technology has an aura of magic about it because it suddenly reveals what had been concealed, and makes visible what had been invisible. So, too, with photoacoustic tomography, which is allowing scientists to virtually peel away the top several inches of flesh to see what lies beneath. The technique achieves this depth vision by an elegant marriage between light and sound, combining...

Discovered a mechanism explaining how tumor cells spread to nearby organs and structures, initiating metastasis Metastasis is responsible for 90% of deaths in patients with cancer. Understanding the mechanisms responsible for this process is one of the top goals of cancer research. The metastatic process involves a series of steps chained where the primary tumour invades surrounding tissues and ends spreading throughout the body. Ones of the first tissues undergoing metastasis are the...

A new study reveals key factors that promote the spread of cancer to lymph nodes and provides a mechanism that explains how a common over-the-counter anti-inflammatory medication can reduce the spread of tumor cells through the lymphatic system. The research, published by Cell Press in the February 14 issue of the journal Cancer Cell, opens new avenues for the design of antimetastatic therapies. The lymphatic system consists of a network of vessels that carry lymphatic fluid from the body...

A lymph node is an immune system organ that is widely distributed throughout various places in the body. There are about 500-600 nodes in an individual adult, with clusters of lymph nodes found in the underarms, groin, neck, chest, and abdomen. The lymphatic system as a whole is responsible for acting as the body’s primary mechanism of defense. Each node is oval-shaped, and measures between a few millimeters and a few centimeters long. They are linked to one another by lymphatic vessels and...
