Histological Evaluation of Epidermal Barrier Function

To evaluate epidermal thickening, the ear and dorsal skin of each mouse was obtained on day 21 and fixed in 10% neutral buffered formalin. Tissues were embedded in paraffin and sliced into 5-μm-thick sections. Sections were then transferred to probe-on-plus slides (Thermo Scientific, Carlsbad, CA, USA), and deparaffinized skin sections were stained with H&E. Mast cells in the skin were stained with toluidine blue. Some sections were stained for immunohistochemical markers using anti-filaggrin (1:1000; ab24584; Abcam), anti-involucrin (1:1000; ab68; Abcam), anti-loricrin (1:1000, ab85679, Abcam), anti-occludin (1:1000; 33-1500; Invitrogen), anti-PAR-2 (1:100; sc-8205, Santa Cruz Biotechnology), and anti-TSLP (1:500; NB110-55234; Novus Biologicals) antibodies. The staining procedure was performed with an Ultravision Quanto Detection System (TL-060-QHD; Thermo Scientific). The slices were washed with PBS, dehydrated and mounted in Permount (SP15-100, Thermo Scientific). All stained sections were then examined by light microscopy (DM750, Leica, Wetzlar, Germany) to assess histological changes. Morphometric analysis (immunostained area of the epidermis to each analyzed protein in relation to total area of the epidermis) was performed using ImageJ 1.51 software (National Institutes of Health, Bethesda, MD, USA). All histological examinations were analyzed in 3 sections/animal slices.

Quantification of PAR2 Expression in Spinal Cord Myelination

To begin to address the significance of PAR2 to myelination of the spinal cord, we quantified the expression of PAR2 RNA in the spinal cord of mice at P0, 7, 21 or 45 using real time PCR (Radulovic et al., 2015 (link)). RNA was isolated using RNA STAT-60 (Tel-Test, Friendswood, TX) and stored at -70 C until the time of analysis. Amplification of the housekeeping gene 18S in the same RNA samples was used to control for loading. Real-time PCR amplification in each case was accomplished using primers obtained from Integrated DNA Technologies (Coralville, IA), or Applied Biosystems (Grand Island, NY), as detailed in Table 1, on an iCycler iQ5 system (BioRad, Hercules, CA). In addition, we localized PAR2 (sc-8205, RRID: AB_2101309, Santa Cruz, Santa Cruz, CA) to Olig2 (Ab9610, RRID:AB_10141047, Millipore, Temecula, CA) or CC-1-postive cells (adenomatous polyposis coli, OP80, RRID:AB_213434, Millipore, Temecula, CA) within the spinal cord white matter at the P21 peak of myelination, using immunofluorescence techniques. Stained sections were cover slipped with Hardset containing DAPI (Vector, Burlingame, CA) and digitally imaged (Olympus BX51 microscope, Olympus, Center Valley, PA). Counts were made of either Olig2 or CC-1+ cells with a DAPI stained nucleus within the entire dorsal column of at least 3 mice at each time point without knowledge of genotype.

Immunodetection of PAR2, TRPV4, and GFAP in Hippocampus

Check if the same lab product or an alternative is used in the 5 most similar protocols
The following primary antibodies were used for immunodetection: goat anti-PAR2 (sc-8205, Santa Cruz, 1:25), rabbit anti-TRPV4 (ACC-124, Alomone Labs, 1:50), rabbit anti-PAR2 (APR-032, Alomone Labs 1:500) and mouse anti-GFAP (G3893, Sigma-Aldrich, 1:2000). Hippocampal sections (50 μm) were blocked in 10% normal horse serum in 0.1 M PBS/0.1% Triton for 1 h at room temperature (RT). After 24–48 h incubation at 4°C with the primary antibody (together with 2% normal horse serum), sections were exposed to the appropriate secondary antibody (DyLightTM 488 conjugated affinity purified donkey anti-goat IgG, 1:800; Alexa Fluor 594 AffiniPure donkey anti-rabbit IgG, 1:2000; Alexa Fluor 488 conjugated AffiniPure donkey anti-mouse IgG, 1:400) for 1 h. The sections were then washed, incubated with Hoechst (b1155, Sigma-Aldrich, 1 μg/ml final concentration) for 10 min (to allow nuclear staining), mounted on dry gelatin-coated slides and finally mounted and cover slipped with Flouromount (F4680, Sigma-Aldrich). Slides were imaged with a Leica SP5 confocal microscope and data were acquired and analyzed using a computer assisted image analysis system.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
