Immune system memory cells may help in long-term fight against ovarian cancer

A study from the Weizmann Institute of Science reveals that memory cells of the immune system do not only work against viruses and bacteria. In women with ovarian cancer, memory B cells were found that are able to reach the tumor and produce antibodies.

A long and winding journey to discover new ways to fight tuberculosis

A study from Tel Aviv University identified two families of human antibodies that bind to the PSTS1 protein of the tuberculosis bacterium, and in a mouse experiment, the antibody treatment led to a 50% reduction in the bacterial load in the lungs.

Immune cells "caught red-handed" – new clues for early detection and possible prevention of type 1 diabetes

Researchers at the University of Pennsylvania analyzed nearly a million immune cells from organ donors, identified a unique subpopulation of CD4 cells in the lymph nodes of the pancreas and changes in B cells in the spleen, and offer a direction for the development of a simple blood test.

The immune cells discovered under the nose

The scientists of the Weizmann Institute of Science have discovered antibody-producing cells in the bone tissue of the nasal concha and thereby plant hope for the development of more effective nasal vaccines and new treatments for allergies and neurological and autoimmune diseases

New information about phagocytic cells of the immune system may lead to treatments for incurable autoimmune diseases

The origin of the mysterious macrophages, known in scientific language as Tingible Body Macrophages (TBM), originates from progenitor cells of the blood system that emerge from the bone marrow and settle in the lymph nodes, where they quickly and efficiently digest cell remnants
