Smokers at higher risk of TB because of 'clogged-up immune cells'

The risk of becoming infected with TB is increased by exposure to smoke from cigarettes and burning fuel. Now, a new study shows this is because smoke clogs up immune cells and weakens their ability to fight TB bacteria. When normal macrophages (green - on the left) become clogged up with cell debris (red - on the right), they lose their ability to engulf TB bacteria. It looks at the effect that smoke particles might have on macrophages - literally the "giant eaters" of the immune system. Macrophages act like "vacuum cleaners" for unwanted material, helping to dispose of and recycle billions of dead cells every day.
