Secreting proteolytic enzymes

The Tropical Thorn Forest at foot hills of Niligris located in Forest College and Research Institute, Mettupalayam under Jackanari Reserve forest, Tamil Nadu, India was scouted and surveyed for the presence and prevalence of Ectomycorrhizal Fungal association. About Twelve different groups of fruiting bodies of ECM fungi were identified and their prevalence index ranged between 40-80% indicating wide diversity and dependency of forest trees on ECM fungi.

Propolis is a natural, resinous, hive product with various bioactive properties. Polymorphonuclear leukocytes (PMNLs) use both oxygen-dependent (respiratory burst) and oxygen-independent mechanisms (releasing proteolytic enzymes such as elastase) to destroy infectious agents.

The importance of proteoglycans for secretionof proteolytic enzymes was studied in the murine macrophage cell line J774. Untreated or 4b-phorbol 12-myristate 13-acetate (PMA)-stimulated macrophages were treated with hexyl-b-D-thioxyloside to interfere with the attachment of glycosaminoglycan chains to their respective protein cores. Activation of the J774 macrophages with PMA resulted in increased secretion of trypsin-like serine proteinase activity.

On chemokine stimulation, leucocytes produce and secrete proteolytic enzymes for innate immunedefencemechanisms. Some of these proteasesmodify the biological activity of the chemokines. For instance, neutrophils secrete gelatinase B (matrix metalloproteinase-9, MMP-9) and neutrophil col-lagenase (MMP-8) after stimulation with interleukin-8/ CXCL8 (IL-8). Gelatinase B cleaves and potentiates IL-8, generating a positive feedback.
