Gelatinase B/MMP-9 activates pro-inflammatory cytokines TNFα and IL-1β, increases the activity of chemokines CXCL1, CXCL4, CXCL7 and CXCL8, releases TGFβ from matrix stores, is released by activated neutrophils in TIMP-1-free form and acts as a nanomolar effector of tumour associated inflammation [12,13]. Here, TIMP1 is linked to neoplasm.
