ICAM1 and lung carcinoma: A literature survey has revealed three significant modes of action; in lung cancer, CBD induces apoptosis via cyclooxygenase 2 (COX2) and PPARɣ signalling, reduces metastasis by upregulating the expression of surface protein intercellular adhesion molecule (ICAM-1), and increases the susceptibility of lung cancer cells to adhere to and subsequently be lysed by lymphokine-activated killer (LAK) cells [2,15,59].
