Additional activities, apart from the recruitment of leukocytes from the blood, are indicated in that the ligation of L-selectin on neutrophils by soluble carbohydrate ligands, such as carcinoma-derived or salivary mucins, potentiates the degranulation of these cells (Shao et al., 2011; Mohanty et al., 2015). The gene discussed is SELL; the disease is carcinoma.
