Insights

Aquaporins (AQPs) are vital proteins regulating water and solute transport. This review explores their role in both infectious and non-infectious diseases, highlighting AQPs as potential therapeutic targets.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Physiology

Background:

  • Aquaporins (AQPs) are integral membrane proteins crucial for transmembrane water and solute transport in all organisms.
  • Humans possess 13 AQPs (AQP0-AQP12), classified into orthodox, aquaglyceroporin, and unorthodox sub-classes based on pore selectivity.
  • AQPs are widely distributed in human tissues and involved in numerous physiological processes.

Purpose of the Study:

  • To review the involvement of aquaporins (AQPs) in infectious and non-infectious diseases.
  • To discuss potential AQPs-target modulators for therapeutic applications.
  • To provide insights into AQP structures, tissue distribution, physiological relevance, functional diversity, and regulation.

Main Methods:

  • Literature review of studies on aquaporins (AQPs) and their association with diseases.
  • Analysis of AQP roles in microbial pathogenesis and inflammation.
  • Synthesis of information on AQP structure, function, and therapeutic potential.

Main Results:

  • Human AQPs are implicated in a wide range of non-infectious diseases, including cancer, renal dysfunction, neurological disorders, and metabolic syndrome.
  • Emerging evidence suggests AQPs are regulated by microbial and parasitic infections, indicating their role in pathogenesis and immune responses.
  • AQPs are involved in maintaining cell water homeostasis during infections.

Conclusions:

  • Aquaporins (AQPs) play significant roles in both infectious and non-infectious diseases.
  • Further investigation of AQPs is warranted to develop them as potential therapeutic targets.
  • Modulating AQP activity offers a promising strategy for treating a diverse spectrum of diseases.

Aquaporins01:25

Aquaporins

Aquaporins or AQPs are a family of integral membrane proteins whose primary function is to transport water, while some called aquaglyceroporins also transport glycerol. In addition, aquaporins have also been suspected to be involved in transporting volatile substances, such as carbon dioxide and ammonia, across membranes. Such AQPs that act as gas channels are often highly expressed in cells involved in the gaseous exchange, such as red blood cells, epithelial cells, and pulmonary capillaries.

Role of Water in Human Biology01:27

Role of Water in Human Biology

Water is the one of the most significant components of the human body; it plays a crucial role in several physiological activities because of its unique physicochemical properties. Importantly, it helps to regulate body temperature and is the chief component of several body fluids.
Water's Solvent Properties
Since water is a polar molecule with slightly positive and slightly negative charges, ions and polar molecules can readily dissolve in it. Therefore, it is referred to as a solvent, a...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Pore Transport and Ion-Pair Transport01:17

Pore Transport and Ion-Pair Transport

Pore transport and ion-pair formation are critical mechanisms for the absorption and distribution of drugs in the body.
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited  but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...

Fluid Movement Between Compartments01:18

Fluid Movement Between Compartments

The force applied by fluids against a surface, known as hydrostatic pressure, initiates the transfer of fluid among different compartments. Within our blood vessels, the blood's hydrostatic pressure is a result of the heart's pumping action. At the arteriolar end of capillaries, hydrostatic pressure (capillary blood pressure) exceeds the opposing colloid osmotic pressure created primarily by plasma proteins like albumin. This discrepancy in pressure propels plasma and nutrients from the...

The Significance of Membrane Transport01:44

The Significance of Membrane Transport

The transport of solutes across the cell membrane is essential for metabolic processes, like maintaining cell size and volume, generating the action potential, exchanging nutrients and gases, etc. Membrane transport can be either passive or active. It can be simple diffusion, facilitated, or mediated transport aided by transport proteins such as transporters and channels.
Transporters facilitate either an active or passive movement of solutes. They can allow a single-molecule transport down its...
