Abstract

Transient receptor potential cation channels of the vanilloid subfamily (TRPV) participate in the generation of Ca2+ signals at different locations of the respiratory system, thereby controlling its correct functioning. TRPV1 expression and activity appear to be altered under pathophysiological conditions such as chronic cough and airway hypersensitivity, whereas TRPV4 single nucleotide polymorphisms (SNP) are associated with chronic obstructive pulmonary disease. However, to date, there is no information about the genetic impact of either TRPV1 or TRPV4 on asthma pathophysiology. We now report on the association of two functional SNPs, TRPV1-I585V and TRPV4-P19S, with childhood asthma. Both SNPs were genotyped in a population of 470 controls without respiratory symptoms and 301 asthmatics. Although none of the SNPs modified the risk of suffering from asthma, carriers of the TRPV1-I585V genetic variant showed a lower risk of current wheezing (odds ratio = 0.51; p = 0.01), a characteristic of active asthma, or cough (odds ratio = 0.57; p = 0.02). Functional analysis of TRPV1-I585V, using the Ca2+-sensitive dye fura-2 to measure intracellular [Ca2+] concentrations, revealed a decreased channel activity in response to two typical TRPV1 stimuli, heat and capsaicin. On the other hand, TRPV4-P19S, despite its loss-of-channel function, showed no significant association with asthma or the presence of wheezing. Our data suggest that genetically determined level of TRPV1 activity is relevant for asthma pathophysiology. © 2010 by The American Society for Biochemistry and Molecular Biology, Inc.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-06-28:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 75.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 75 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
Continuing with the social impact of the work, it is important to emphasize that, due to its content, it can be assigned to the area of interest of ODS 3 - Good Health And Well-being, with a probability of 83% according to the mBERT algorithm developed by Aurora University.
