Toxins from diseased brain cells make diseases of the brain even worse
Sometimes our immune defence attacks our own cells. When this happens in the brain we see neurodegenerative diseases such as dementia, Alzheimer's and Parkinson's disease. But if the the immune defence is inhibited, the results ...

Call of the riled: Stress signal in cancer cells triggers similar response in other cells, aiding tumor growth
Researchers at the University of California, San Diego School of Medicine say a "stress response" mechanism used by normal cells to cope with harsh or demanding conditions is exploited by cancer cells, which ...

Making viruses pass for 'safe'
Viruses can penetrate every part of the body, making them potentially good tools for gene therapy or drug delivery. But with our immune system primed to seek and destroy these foreign invaders, delivering therapies with viruses ...

An Alzheimer's vaccine in a nasal spray
One in eight Americans will fall prey to Alzheimer's disease at some point in their life, current statistics say. Because Alzheimer's is associated with vascular damage in the brain, many of them will succumb through a painful ...

Breast cancer cells outsmart the immune system and thrive
Scientists discovered a new way breast cancer cells dodge the immune system and promote tumor growth, providing a fresh treatment target in the fight against the disease. While comparable mechanisms to avoid the immune system ...

Scientists find the 'master switch' for key immune cells in inflammatory diseases
(PhysOrg.com) -- Scientists have identified a protein that acts as a "master switch" in certain white blood cells, determining whether they promote or inhibit inflammation. The study, published in the journal ...

Steering cancer inflammation to inhibit tumor growth and spread
Most cancer tissues are invaded by inflammatory cells that either stimulate or inhibit the growth of the tumor, depending on what immune cells are involved. Now a Swedish-Belgian research team has shown that a protein that ...

Macrophage
Macrophages (Greek: big eaters, from makros "large" + phagein "eat"; abbr. MΦ) are white blood cells within tissues, produced by the division of monocytes. Human macrophages are about 21 micrometres in diameter. Monocytes and macrophages are phagocytes, acting in both non-specific defense (or innate immunity) as well as to help initiate specific defense mechanisms (or adaptive immunity) of vertebrate animals. Their role is to phagocytose (engulf and then digest) cellular debris and pathogens either as stationary or as mobile cells, and to stimulate lymphocytes and other immune cells to respond to the pathogen. They can be identified by specific expression of a number of proteins including CD14, CD11b, F4/80 (mice)/EMR1 (human), Lysozyme M, MAC-1/MAC-3 and CD68 by flow cytometry or immunohistochemical staining. They move by action of Amoeboid movement.
