The binding of host PLG or plasmin might represent a mechanism to regulate several physiological processes, e.g., fibrinolysis, ECM degradation, cell migration, the processing of growth factors, and bacterial metastasis into several organs [44].
Isoniazid, ethionamide, and pyrazinamide are similar in structure to nicotinamide adenine dinucleotide (NAD), a coenzyme essential for several physiological processes.
Nitric oxide (NO) is a signal molecule involved in several physiological processes in plants, including root development.
Temperature and salinity are important factors that affect several physiological processes in aquatic organisms, which could be produced by variation of certain hormones.
Sulfur dioxide (SO2) can be endogenously produced by enzymes in mitochondria during oxidation of H2S or sulphur-containing amino acids, and plays important roles in several physiological processes.
Serine protease inhibitors (PIs) are involved in several physiological processes, such as regulation of endogenous proteinases and defence against phytophageous insects.
These ions play diverse roles in bio-systems and their concentration in extracellular as well as in intracellular fluids should be known to understand several physiological processes.
Dehydroepiandrostenedione (DHEA), a 17-ketosteroid hormone produced by adrenal glands, gonads and including gastrointestinal tract is required for several physiological processes.
The enzyme tissue transglutaminase 2 (TG2) appears to play an important role in several physiological processes such as wound healing, the progression of cancer and of vascular disease.
Ethylene influences directly several physiological processes and stimulates the production of endogenous ethylene.
However, CGRP and its receptor are abundantly present in both the vasculature, and in the peripheral and central nervous system, and are involved in several physiological processes.
