Fig. 3From: Modulation of pulmonary immune function by inhaled cannabis products and consequences for lung diseaseDiffering biological and physiological features of macrophage subsets. Monocytes stimulated by macrophage-colony stimulating factor (M-CSF) differentiate into M0 macrophages. M0 macrophages subjected to certain stimuli promote a phenotype of either M1, M2a, M2b, M2c, or M2d. Each phenotype has characteristic cytokine/chemokine secretion profiles with respective cellular and molecular functions; adapted from [196]Back to article page
