Supertrends in Aquaporin & Sepsis discusses the implications of aquaporins (AQP) in healthcare, particularly with regard to the challenges and opportunities we face in sepsis, and the potential role that AQPs could play in sepsis management. For investors, policy makers, healthcare providers, and entrepreneurs, this report offers insights in both topics and a novel approach in combining the two concepts to explore new solutions.
An introduction into aquaporins and their implication in health with some of the latest discoveries
An analysis of the challenges in sepsis management we face today, and opportunities aquaporin-based therapy could offer
A timeline detailing historical as well as expected future milestones in aquaporin and sepsis research
An outlook on the prospects for using aquaporins as a new approach for sepsis management
An overview on the definition, pathophysiology and management of sepsis
Water is one of the essential elements on earth. All plants, animals, and humans must have water to survive. Nevertheless, there are still mysteries surrounding the way water is conveyed through the human body. For hundreds of years, scientists have wondered how water molecules are selectively transported through cell membranes. The secret of aquaporins was eventually discovered in 1992 by Peter Agre, who won the 2003 Nobel Prize in Chemistry for his discovery and investigation of the water channels.
Our focus in the following is on the potential of aquaporins modulators as a novel approach to treating sepsis; a discussion of the full spectrum of aquaporins’ implications for health and disease is beyond the scope of this report.
In the following, we offer two timelines listing some important milestones that have assisted researchers’ understanding of sepsis, as well as landmark discoveries related to AQPs and their implications for health. Neither the present report nor these timelines aim to include all the events that have happened or are happening in the two fields. The aim is to illustrate the future trends in these areas and the interaction between them.
Sepsis is one of the oldest syndromes to be described and named in the discipline of medicine. It is also one of the deadliest and costliest diseases, yet public awareness of sepsis remains poor. Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection.
Aquaporins are a family of membrane water channel proteins that osmotically modulate water fluid homeostasis in several tissues; some of them also transport small solutes such as glycerol. The human body expresses 13 AQPs with specific organ, tissue, and cellular localization. The regulation of AQPs takes place either through gating or through controlled transport and integration to specific membrane compartments. AQPs are involved in inflammation, water balance disorders, brain oedema, cancer, and many other health conditions.
In connection with emerging present-day infections, such as HIV/AIDS, SARS, Ebola, and COVID-19, viral sepsis is becoming an ever-greater challenge. The elevated cytokine levels and hyper-inflammatory reaction appear as a dominant element in some of the cases. Can an AQP-based therapy be part of the answer to sepsis? This question is most likely to be answered with a personalized approach.
AQPs are involved in fundamental cellular and body functions. A loss of function or dysregulated function of AQPs would lead to pathological conditions. In chapter 4. we have described the consequences of losing AQP function. Here we want to assess where clinical translation currently stands. One of the promising approaches for AQP -based therapy is to develop small chemical molecules that modulate the function of AQPs.
Big data analysis and precision medicine may provide future direction for upcoming research in sepsis. With the new approach of aquaporin-based therapy, we may have a drug that specifically targets dysregulated immune function in sepsis before the end of this decade.
