Galectin binding proteins in serum and bronchoalveolar lavage -in healthy and pathological conditions

Cederfur, Cecilia

Galectins are carbohydrate binding proteins, implicated in conditions of both inflammation and cancer. Connections between chronic inflammation and cancer are proposed by the increased remodelling and proliferation that occurs, leading to enhanced survival and proliferation of malignant cells. Since...
