Trained immunity – a process being explored in vaccine and therapy development to boost immune defences – appears be counterproductive in certain contexts, researchers at ��ϲ�� University and the Research Institute of the ��ϲ�� University Health Centre (The Institute) have found.

Trained immunity is when the body’s first line of defence remembers past threats and becomes more reactive, responding more strongly to future infections even if they are different, by changing how immune cells behave.

Why do some non-smokers get COPD while many heavy smokers don’t?

Smoking is the best-known risk factor for chronic obstructive pulmonary disease (COPD), a debilitating lung condition that can severely limit a person’s day-to-day activities. But curiously, only a minority of lifelong smokers develops the disease, while non-smokers represent more than 25% of all COPD cases. A new study published today in The Journal of the American Medical Association suggests that a developmental mismatch between airway and lung size—a condition called dysanapsis—could answer why.

The internal anatomy of our lungs is surprisingly variable, and some of those variations are associated with a greater risk of chronic obstructive pulmonary disease (COPD), a new study led by researchers at ��ϲ�� University and the Columbia University Irving Medical Center has found.
