TRPV4 Activation Increases the Expression of CD207 (Langerin) of Monocyte-Derived Langerhans Cells without Affecting their Maturation. J Invest Dermatol 2022; 143:801-811.e10.

Abstract
Langerhans cells (LCs) are the sole professional antigen-presenting cell normally found in the human epidermal compartment. Research into their physiological role is hindered by the fact that they are invariably activated during isolation from the skin. To overcome this challenge, we turned to a monocyte-derived LC (moLC) model, which we characterized with RNA sequencing, and compared the transcriptome of moLCs with that of donor-matched immature dendritic cells. We found that moLCs express markers characteristic of LC2 cells as well as TRPV4. TRPV4 is especially important in the skin because it has been linked to the conservation of the skin barrier, immunological responses, as well as acute and chronic itch, but we know little about its function on LCs. Our results show that TRPV4 activation increased the expression of Langerin and led to increased intracellular calcium concentration in moLCs. Regarding the functionality of moLCs, we found that TRPV4 agonism had a mitigating effect on their inflammatory responses because it decreased their cytokine production and T-cell activating capability. Because TRPV4 has emerged as a potential therapeutic target in dermatological conditions, it is important to highlight LCs as, to our knowledge, a previously unreported target of these therapies.

Abstract
Since Unna's Abtropfung hypothesis, the process of migration of nevus cells in the dermis remains unknown. To investigate its mechanisms, we studied the role of gelatinases in dermal nevus cells obtained from congenital pigmented nevi, which are major actors in the remodeling of basement membrane proteins. Our previous studies have shown that dermal nevus cells express pro-matrix metalloproteinase (MMP)-2 exclusively and cannot return to the dermis when seeded together with keratinocytes on top of the dermis in a skin reconstruction model. To examine why MMP-2 was not in its active form, we used Western blot to study the expression of members of the MMP-2 activation pathway (membrane type 1-MMP and tissue inhibitor of metalloproteinase-2), which proved to be normally expressed. To induce the dermal passage of nevus cells artificially, we also tried to activate gelatinases with phorbol-12-myristate-13-acetate and epidermal growth factor, using epidermis reconstructed with nevus cells. No migration in the dermis could be triggered. We conclude that the absence of active MMP-2 is due to a functional blockade of its activation pathway and may prevent dermal nevus cells from reaching the dermal compartment in skin reconstructs. Furthermore, our findings reinforce the concept that dermal nevus cells originating from congenital nevi are in a quiescent status.

Abstract
BACKGROUND We know little of the initial events during the sensitization phase of contact allergy in humans. Alopecia areata (AA), a disease of unknown pathogenesis characterized by patchy hair loss, may be treated by inducing contact allergy to diphenylcyclopropenone (DPC), later followed by its topical application. OBJECTIVES To learn more about the initial events during sensitization in human skin, we studied the early events during induction of contact allergy to DPC in patients with AA. METHODS DPC 2% and sodium lauryl sulphate (SLS) 4% were applied on the backs of eight patients with AA. Punch biopsies were taken 6 and 24 h after application. The biopsies were snap-frozen and cryostat sections were evaluated with immunohistochemistry using antibodies against CD1a, HLA-DR, CD3, CD54 and matrix metalloproteinase 9 (MMP-9). RESULTS After 24 h all subjects exhibited erythema on the DPC-treated areas. Histological evaluation of biopsies from these areas showed hydropic degeneration and a significantly increased number of MMP-9+ cells in the dermis (P < 0.0005). The MMP-9+ cells were identified with double immunofluorescence staining as CD1a + Langerhans cells. The expression of the other markers studied remained unaltered irrespective of treatment, including treatment with SLS. CONCLUSIONS Our findings show that DPC induces an irritant reaction leading to an increased number of MMP-9+ CD1a+ cells in the dermis during the initial phase of sensitization.

Abstract
Langerhans cells (LC) are dendritic cells that capture foreign antigens and migrate with them to the regional lymph nodes where they are presented to naive T cells. The possible role of matrix metalloproteinase-9 (MMP-9) in migration was suggested following experiments in a mouse model and in human skin explants. Using in vitro generated LC (iLC) derived from CD34+ cord blood cells and epidermal LC (eLC), we investigated the correlation between MMP-9 and other MMPs production and cell migration. Cells were activated by Bandrowski's base (BB), a chemical allergen, or by recombinant birch pollen allergen 1 (rBetv 1). Contact with allergens triggered migration of these cells, with a maximum rate being reached after 24 h. Migration was preceded by production of MMP-2 and MMP-9; part of the molecules were recovered as pro-MMPs in cell culture supernatant and part were associated with cell membrane proteins. At the cellular level, membrane-type 1 (MT1) and MT3-MMP were also identified. Addition of tumor necrosis factor-alpha (TNF-alpha) initiated pro-MMP-2 and pro-MMP-9 production followed by cell migration in a dose-dependent manner. These data imply that TNF-alpha is a key molecule for MMP production and cell migration. Furthermore, activation of iLC with BB or rBet v 1 induced synthesis of TNF-a and expression of TNF RII on the cell membrane, suggesting an autocrine loop. In conclusion, membrane-associated MMP-2 and-9 rather than soluble MMPs appear to be involved in cell migration.

Abstract
Dendritic cells migrate from the skin to the draining lymph nodes. They transport immunogenic MHC-peptide complexes, present them to Ag-specific T cells in the T areas, and thus generate immunity. Migrating dendritic cells encounter physical obstacles, such as basement membranes and collagen meshwork. Prior work has revealed that matrix metalloproteinase-9 (MMP-9) contributes to mouse Langerhans cell migration. In this study, we use mouse and human skin explant culture models to further study the role of MMPs in the migration and maturation of skin dendritic cells. We found that MMP-2 and MMP-9 are expressed on the surface of dendritic cells from the skin, but not from other sources. They are also expressed in migrating Langerhans cells in situ. The migration of both Langerhans cells and dermal dendritic cells is inhibited by a broad spectrum inhibitor of MMPs (BB-3103), by Abs to MMP-9 and -2, and by the natural tissue inhibitors of metalloproteinases (TIMP), TIMP-1 and TIMP-2. Inhibition by anti-MMP-2 and TIMP-2 define a functional role for MMP-2 in addition to the previously described function of MMP-9. The importance of MMP-9 was emphasized using MMP-9-deficient mice in which Langerhans cell migration from skin explants was strikingly reduced. However, MMP-9 was only required for Langerhans cell migration and not maturation, since nonmigrating Langerhans cells isolated from the epidermis matured normally with regard to morphology, phenotype, and T cell stimulatory function. These data underscore the importance of MMPs, and they may be of relevance for therapeutically regulating dendritic cell migration in clinical vaccination approaches.

Abstract
We studied the secretion of gelatinase B by dendritic cells (DC) generated by culturing human peripheral blood monocytes in granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4). First, we found the intracellular expression of gelatinase B on sections of fixed DC pellets. Zymography analysis of the supernatants of DC cultured for 72 h demonstrated the presence of gelatinase B. To determine if DC produce net enzymatic activity, bioactive gelatinase, a novel sensitive fluorescent-activated substrate conversion (FASC) assay was used to complement the zymography data. Culture media of unstimulated DC demonstrated reproducible net gelatinolytic activity. Tumor necrosis factor-alpha (TNF-alpha) IL-1beta but not lipopolysaccharide (LPS) stimulation caused a significant increase in gelatinase B production in zymography analysis. Both types of stimulation failed to increase net gelatinase activity in FASC assay. Interestingly, interferon-beta (IFN-beta) significantly diminished both the total zymolytic production and the net bioactive gelatinase produced by DC in a dose-dependent manner. We conclude that human monocyte-derived DC secrete bioactive gelatinase B and that IFN-beta inhibits this production.

Abstract
Dendritic cells are leukocytes of bone marrow origin. They are central to the control of the immune response. Dendritic cells are highly specialized in processing and presenting antigens (microbes, proteins) to helper T lymphocytes. Thereby, they critically regulate further downstream processes such as the development of cytotoxic T lymphocytes, the production of antibodies by B lymphocytes, or the activation of macrophages. A new field of dendritic cell biology is the study of their potential role in inducing peripheral tolerance. The immunogenic/tolerogenic potential of dendritic cells is increasingly being utilized in immunotherapy, particularly for the elicitation of antitumor responses. One very important specialization of dendritic cells is their outstanding capacity to migrate from sites of antigen uptake to lymphoid organs. Much has been learned about this process from studying one particular type of dendritic cell, namely, the Langerhans cell of the epidermis. Therefore, the migratory properties of Langerhans cells are reviewed. Knowledge about this "prototype dendritic cell" may help researchers to understand migration of other types of dendritic cells.

Abstract
In the present study, Langerhans' cells (LCs) in the sacral epidermis, 8-10 cm from lesions of patients (mean age 71 years) with decubital ulcers, were compared ultrastructurally and morphometrically with those in the patients' own normal epidermis from the upper leg, before and after supplementation with 50 mg/day elementary zinc (in the form of a 220-mg tablet of Avazinc, administered once daily) for four months. Zinc intake resulted in from 80% to full healing of the decubital ulcers in the patients studied. The percentages of LCs were low in both perilesional sacral epidermis (2.07 +/- 0.71%) and in control leg epidermis (2.71 +/- 1.38%) before zinc supplementation and also afterward (2.12 +/- 0.16% and 2.59 +/- 0.88%, respectively). LCs demonstrated a more dendritic morphology after zinc supplementation: 68.15 +/- 9.28% and 77.0 +/- 3.45% of sacral and of control leg epidermal LCs, respectively, had dendrites before, and 91.52 +/- 3.43% and 84.15 +/- 3.64% of sacral and of control leg epidermal LCs, respectively, had dendrites after zinc supplementation. The LC section area in the sacral epidermis near the lesion as well as in the control leg epidermis and the number of LC granules in LC sections were not affected by zinc supplementation. The higher percentage of LCs having dendrites in the epidermis of patients with decubital ulcers after zinc supplementation may indicate that these LCs are in a more motile state, which might affect the healing process of the lesions.

Abstract
Langerhans cells (LC) are members of the wider family of dendritic cells. LC reside in the epidermis where they serve as sentinels of the immune system, their responsibilities being to sample the external environment for changes and challenges and to deliver information (antigen) to responsive T lymphocytes within skin draining lymph nodes. The ability of LC to migrate from the epidermis to regional lymph nodes is therefore of pivotal importance to the induction of cutaneous immune responses. The journey that LC have to make from the skin has a number of requirements. Initially it is necessary that LC disassociate themselves from surrounding keratinocytes and are liberated from other influences that encourage their retention in the epidermis. Subsequently, migrating LC must successfully traverse the basement membrane of the dermal-epidermal junction and make their way, via afferent lymphatics, to draining lymph nodes. Effective entry into lymph nodes is necessary, as is correct positioning of cells within the paracortex. There is increasing evidence that both cytokines and chemokines, and their interaction with appropriate receptors expressed by LC, orchestrate the mobilization and movement of these cells. We here consider the parts played by these molecules, and how collectively they induce and direct LC migration.

Abstract
Abstract
Epidermal Langerhans cells (LC) are potent dendritic cells in the induction of primary T cell-mediated immune responses in the skin. They capture foreign Ags and migrate to regional lymph nodes to carry and present these Ags to naive T cells. We investigated the role of matrix metalloproteinase-9 (MMP-9) in LC migration using an anti-MMP-9 mAb. Intradermal injection of anti-MMP-9 mAb before rhodamine B or oxazolone painting markedly inhibited these hapten-induced decreases in LC number in the epidermis and the accumulation of dendritic cells in the regional lymph nodes, indicating that MMP-9 plays some important roles in LC migration in the induction phase of contact sensitization. Treatment with anti-MMP-9 mAb also blocked the increase in cell size, dendrite development, and the enhanced expression of MHC class II Ags in LC induced by hapten painting. In addition, intradermal injection of purified MMP-9 induced marked increases in cell size, dendrite extension, and enhanced expression of MHC class II Ags in LC. These results strongly suggested that MMP-9 is involved not only in LC migration, but also in their morphological and phenotypic maturation in the skin.
