Abstract
Fibroblasts are an important subset of mesenchymal cells in maintaining skin homeostasis and resisting harmful stimuli. Meanwhile, fibroblasts modulate immune cell function by secreting cytokines, thereby implicating their involvement in various dermatological conditions such as psoriasis, vitiligo, and atopic dermatitis. Recently, variations in the subtypes of fibroblasts and their expression profiles have been identified in these prevalent autoimmune skin diseases, implying that fibroblasts may exhibit distinct functionalities across different diseases. In this review, from the perspective of their fundamental functions and remarkable heterogeneity, we have comprehensively collected evidence on the role of fibroblasts and their distinct subpopulations in psoriasis, vitiligo, atopic dermatitis, and scleroderma. Importantly, these findings hold promise for guiding future research directions and identifying novel therapeutic targets for treating these diseases.

Microb Pathog 2022; 166:105555. [PMID: 35487480 DOI: 10.1016/j.micpath.2022.105555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 03/17/2022] [Accepted: 04/22/2022] [Indexed: 11/28/2022]
Abstract
Vulvovaginal candidiasis (VVC), a major gynecological disease with high recurrence rate, increases the risk of abortion, intrauterine infection, premature rupture of membranes, and premature birth in pregnancy. However, the exact pathogenesis of this disease has yet to be elucidated. To facilitate understanding of the pathogenesis of VVC in pregnancy, this study sought to establish an animal model of vaginal infection with Candida albicans in pregnant mice. Female mice were mated with male mice, and female mice were infected with C. albicans at E4.5 (embryonic day 4.5). The weight and abortion rate of pregnant mice at E0.5, E4.5, E8.5, E11.5, and E18.5 were recorded, respectively, as well as the weights of fetus and placenta on E18.5. Fetal weight at E18.5 and the weight growth rate in the experimental mice was lower than those in the control mice, but the placenta weight at E18.5 and the abortion rate in the experimental mice were increased with those of the control mice. Hematoxylin-eosin (H&E) staining, Gomori-Grocott staining and vaginal lavage culturing were conducted to verify that the experimental mice were infected with C. albicans. Differentially expressed gene IL-15 was screened out by polymerase chain reaction (PCR) array between the two groups. Enzyme-linked immunosorbent assay (ELISA) showed that IL-15 expression in plasma of the mice was decreased in the experimental group compared with the control group. RT-qPCR confirmed that IL-15 mRNA expression was increased in placental tissues, while mRNA expression of IL-15R/JAK1-JAK3/PI3K/PDK1/AKT/P70S6K-mTOR was decreased in placental tissues. In conclusion, this study demonstrated that VVC in BALB/c pregnant mice led to a series of adverse pregnancy outcomes that were related to changes in IL-15 and its downstream signaling pathways, which may indicate a potential therapy for VVC during pregnancy in humans.

Abstract
Inflammatory skin diseases including atopic dermatitis (AD) and psoriasis (PSO) are underpinned by dendritic cell (DC)-mediated T cell responses. Currently, the heterogeneous human cutaneous DC population is incompletely characterized, and its contribution to these diseases remains unclear. Here, we performed index-sorted single-cell flow cytometry and RNA sequencing of lesional and nonlesional AD and PSO skin to identify macrophages and all DC subsets, including the newly described mature LAMP3+BIRC3+ DCs enriched in immunoregulatory molecules (mregDC) and CD14+ DC3. By integrating our indexed data with published skin datasets, we generated a myeloid cell universe of DC and macrophage subsets in healthy and diseased skin. Importantly, we found that CD14+ DC3s increased in PSO lesional skin and co-produced IL1B and IL23A, which are pathological in PSO. Our study comprehensively describes the molecular characteristics of macrophages and DC subsets in AD and PSO at single-cell resolution, and identifies CD14+ DC3s as potential promoters of inflammation in PSO.

Atwa MA, Ali SMM, Youssef N, Mahmoud Marie RES. Elevated serum level of interleukin-15 in vitiligo patients and its correlation with disease severity but not activity. J Cosmet Dermatol 2020; 20:2640-2644. [PMID: 33355977 DOI: 10.1111/jocd.13908] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 12/05/2020] [Accepted: 12/09/2020] [Indexed: 01/24/2023]
Abstract
BACKGROUND Vitiligo is a common acquired disorder of depigmentation. Its pathogenesis entails a T helper (Th) 1-cytotoxic T (cT) lymphocytes mediated autoimmune melanocyte destruction. Interleukin (IL)-15 is one of the IL-2 family of cytokines and shares several actions with IL-2. IL-15 enhances survival, maturation, and functional activity of natural killer, neutrophils, and dendritic cells. Furthermore, it potentiates survival, maturation, and cytotoxicity of memory cT cells. IL-15 has been shown to play a crucial role in the pathogenesis of several autoimmune diseases but was poorly investigated in patients with vitiligo. AIMS The study aimed at evaluating IL-15 level in the sera of patients with vitiligo and its association with vitiligo severity and activity. PATIENTS AND METHODS The study included 30 patients with nonsegmental vitiligo and 30 healthy controls. Vitiligo Extent Score (VES) and Vitiligo Disease Activity (VIDA) score were used to assess vitiligo severity and activity, respectively. Serum level of IL-15 was assessed by enzyme-linked immune-sorbent assay. RESULTS Serum IL-15 level, in patients with vitiligo, was significantly higher in comparison with the control group (P = .001). A significant positive correlation was found between serum IL-15 level and VES score (P = .001), whereas there was no significant correlation between IL-15 level and VIDA score as well as the disease duration. CONCLUSION IL-15 level was elevated in the sera of patients with vitiligo. IL-15 may therefore have a significant impact on vitiligo autoimmune pathogenesis, and further identification of its molecular roles may highlight new therapeutic strategies for vitiligo.
