Photoreceptors for a light biotransducer: a comparative study of the electrical responses of two (type-1)-opsins

open access: yes, 2013
The increasing interest in photoactivated proteins as natural replacement of standard inorganic materials in photocells drives to the compared analysis of bacteriorhodopsin and proteorhodopsin, two widely diffused proteins belonging to the family of ...

Light‐Based Molecular Tools to Precisely Monitor and Operate β‐Adrenoceptors

open access: yesMedicinal Research Reviews, Volume 46, Issue 2, Page 445-474, March 2026.
ABSTRACT β‐Adrenoceptors are important G protein–coupled receptors involved in cardiovascular, metabolic, and neurological regulation. To study their function with high precision, light‐based molecular tools have been developed offering precise spatiotemporal control.

Ultraviolet and violet receptors express identical mRNA encoding an ultraviolet-absorbing opsin: Identification and histological localization of two mRNAs encoding short-wavelength-absorbing opsins in the retina of the butterfly Papilio xuthus [PDF]

open access: yes, 2000
This paper describes the primary structures of two opsins of short-wavelength-absorbing visual pigments deduced from the mRNA sequences in the retina of the Japanese yellow swallowtail butterfly Papilio xuthus.

Human Cyclophilins—An Emerging Class of Drug Targets

open access: yesMedicinal Research Reviews, Volume 46, Issue 2, Page 475-512, March 2026.
ABSTRACT Cyclophilins are a family of enzymes with peptidyl‐prolyl isomerase activity found in all cells of all organisms. To date, 17 cyclophilin isoforms have been identified in the human body, participating in diverse biological processes. Consequently, cyclophilins have emerged as promising targets for drug development to address a wide array of ...

Opsin evolution and expression in Arthropod compound Eyes and Ocelli: Insights from the cricket Gryllus bimaculatus

open access: yesBMC Evolutionary Biology, 2012
Background Opsins are key proteins in animal photoreception. Together with a light-sensitive group, the chromophore, they form visual pigments which initiate the visual transduction cascade when photoactivated.

Polarization vision and the physiological basis for trichromatic vision in Philaenus spumarius: Understanding host‐seeking behaviour in insect vectors for Xylella fastidiosa control

open access: yesAnnals of Applied Biology, Volume 188, Issue 2, Page 503-519, March 2026.
We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...

Visual Function Assessment in Geographic Atrophy: A Review

open access: yesClinical &Experimental Ophthalmology, Volume 54, Issue 2, Page 260-274, March 2026.
ABSTRACT Geographic atrophy (GA) causes significant vision impairment and reduction in vision‐related quality of life. Fundus autofluorescence (FAF) is the gold standard of structural assessment of GA but is a surrogate marker for vision loss, which can be assessed by tests of visual function and functional vision.
