A fluorescence imaging technique suggests that sweat leakage in the epidermis contributes to the pathomechanism of palmoplantar pustulosis. Sci Rep 2024; 14:378.

Abstract
Sweat is an essential protection system for the body, but its failure can result in pathologic conditions, including several skin diseases, such as palmoplantar pustulosis (PPP). As reduced intraepidermal E-cadherin expression in skin lesions was confirmed in PPP skin lesions, a role for interleukin (IL)-1-rich sweat in PPP has been proposed, and IL-1 has been implicated in the altered E-cadherin expression observed in both cultured keratinocytes and mice epidermis. For further investigation, live imaging of sweat perspiration on a mouse toe-pad under two-photon excitation microscopy was performed using a novel fluorescent dye cocktail (which we named JSAC). Finally, intraepidermal vesicle formation which is the main cause of PPP pathogenesis was successfully induced using our "LASER-snipe" technique with JSAC. "LASER-snipe" is a type of laser ablation technique that uses two-photon absorption of fluorescent material to destroy a few acrosyringium cells at a pinpoint location in three-dimensional space of living tissue to cause eccrine sweat leakage. These observatory techniques and this mouse model may be useful not only in live imaging for physiological phenomena in vivo such as PPP pathomechanism investigation, but also for the field of functional physiological morphology.

Abstract
In situ hybridization (ISH) is a powerful method for detecting specific RNAs at the cellular level. Although conventional ISH using hapten-labeled probes are useful for detecting multiple RNAs, the detection procedures are still complex and required longer time. Therefore, we introduced a new application of fluorescence resonance energy transfer (FRET)-based molecular beacon (MB) probes for ISH. MCF-7 cells and C57BL/6J mouse uterus were used for ISH. MB probes for ERα mRNA and 28S rRNA were labeled with Cy3/BHQ-2 and 6-FAM/DABCYL, and conventional probes were labeled with digoxigenin. Fluorescence measurements revealed that of more-rapid hybridization kinetics compared to conventional probes. In MCF-7 cells, 28S rRNA was detected in nucleolus and cytoplasm of all cells, whereas ERα mRNA was detected in some nucleolus. In the uterus, 28S rRNA was clearly detected using complementary MB probe, but there were no signals in control slides. Moreover, 28S rRNA was detected in all cells, whereas ERα mRNA was detected mainly in the epithelium. Fluorescence intensity of 28S rRNA was decreased significantly in 1 or 2 base-mismatched sequences, that indicates highly specific detection of target RNAs. In conclusion, the FRET-based MB probes are very useful for ISH, providing rapid hybridization, high sensitivity and specificity.

Abstract
Solvatochromic dyes have emerged as a new class of fluorescent probes in the field of lipid membranes due to their ability to identify the lipid organization of biomembranes in live cells by changing the color of their fluorescence. This type of solvatochromic function is useful for studying the heterogeneous features of biomembranes caused by the uneven distribution of lipids and cholesterols in live cells and related cellular processes. Therefore, a variety of advanced solvatochromic dyes have been rapidly developed over the last decade. To provide an overview of the works recently developed solvatochromic dyes have enabled, we herein present some solvatochromic dyes, with a particular focus on those based on pyrene and Nile red. As these dyes exhibit preferable photophysical properties in terms of fluorescence microscopy applications and unique distribution/localization in cellular compartments, some have already found applications in cell biological and biophysical studies. The goal of this review is to provide information to researchers who have never used solvatochromic dyes or who have not discovered applications of such dyes in biological studies.
