Abstract
Overlapping clinical and pathomechanistic features can complicate the diagnosis and treatment of inflammatory skin diseases, including psoriasis and atopic dermatitis (AD). Spatial transcriptomics allows the identification of disease- and cell-specific molecular signatures that may advance biomarker development and future treatments. This study identified transcriptional signatures in keratinocytes and sub-basal CD4+ and CD8+ T lymphocytes from patients with psoriasis and AD. In silico prediction of ligand:receptor interactions delivered key signalling pathways (interferon, effector T cells, stroma cell and matrix biology, neuronal development, etc.). Targeted validation of selected transcripts, including CCL22, RELB, and JUND, in peripheral blood T cells suggests the chosen approach as a promising tool also in other inflammatory diseases. Psoriasis and AD are characterized by transcriptional dysregulation in T cells and keratinocytes that may be targeted therapeutically. Spatial transcriptomics is a valuable tool in the search for molecular signatures that can be used as biomarkers and/or therapeutic targets.

Abstract
Sjögren's disease (SjD) is an autoimmune disease that affects exocrine tissues and is characterized by increased apoptosis in salivary and lacrimal glands. Although the pathogenic mechanism triggering SjD is not well understood, overexpression of lysosome-associated membrane protein 3 (LAMP3) is associated with the disease in a subset of SjD patients and the development of SjD-like phenotype in mice. In this study, histological analysis of minor salivary glands of SjD patients suggested that LAMP3-containing material is being ejected from cells. Follow-on in vitro experiments with cells exposed to extracellular particles (EPs) derived from LAMP3-overexpressing cells showed increased apoptosis. Proteomics identified LAMP3 as a major component of EPs derived from LAMP3-overexpressing cells. Live-cell imaging visualized release and uptake of LAMP3-containing EPs from LAMP3-overexpressing cells to naïve cells. Furthermore, experiments with recombinant LAMP3 protein alone or complexed with Xfect protein transfection reagent demonstrated that internalization of LAMP3 was required for apoptosis in a caspase-dependent pathway. Taken together, we identified a new role for extracellular LAMP3 in cell-to-cell communication via EPs, which provides further support for targeting LAMP3 as a therapeutic approach in SjD.

Abstract
BACKGROUND Dendritic cells (DCs) specific intercellular adhesion molecule (ICAM)-3-grabbing non integrin receptor (DC-SIGN) binds to subgenera Leishmania promastigotes mediating its interaction with DC and neutrophils, potentially influencing the infection outcome. OBJECTIVES In this work, we investigated whether DC-SIGN receptor is expressed in cells from cutaneous leishmaniasis (CL) lesions as well as the in vitro binding pattern of Leishmania (Viannia) braziliensis (Lb) and L. (L.) amazonensis (La) promastigotes. METHODS DC-SIGN receptor was labeled by immunohistochemistry in cryopreserved CL tissue fragments. In vitro binding assay with CFSE-labeled Lb or La promastigotes and RAJI-transfecting cells expressing DC-SIGN (DC-SIGNPOS) or mock-transfected (DC-SIGNNEG) were monitored by flow cytometry at 2 h, 24 h and 48 h in co-culture. RESULTS In CL lesion infiltrate, DC-SIGNPOS cells were present in the dermis and near the epidermis. Both Lb and La bind to DC-SIGNPOS cells, while binding to DC-SIGNNEG was low. La showed precocious and higher affinity to DC-SIGNhi population than to DC-SIGNlow, while Lb binding was similar in these populations. CONCLUSION Our results demonstrate that DC-SIGN receptor is present in L. braziliensis CL lesions and interact with Lb promastigotes. Moreover, the differences in the binding pattern to Lb and La suggest DC-SIGN can influence in a difference way the intake of the parasites at the first hours after Leishmania infection. These results raise the hypothesis that DC-SIGN receptor could participate in the immunopathogenesis of American tegumentary leishmaniasis accounting for the differences in the outcome of the Leishmania spp. infection.

Novel epoxy-tiglianes stimulate skin keratinocyte wound healing responses and re-epithelialization via protein kinase C activation. Biochem Pharmacol 2020; 178:114048.

Abstract
Epoxy-tiglianes are a novel class of diterpene esters. The prototype epoxy-tigliane, EBC-46 (tigilanol tiglate), possesses potent anti-cancer properties and is currently in clinical development as a local treatment for human and veterinary cutaneous tumors. EBC-46 rapidly destroys treated tumors and consistently promotes wound re-epithelialization at sites of tumor destruction. However, the mechanisms underlying these keratinocyte wound healing responses are not completely understood. Here, we investigated the effects of EBC-46 and an analogue (EBC-211) at 1.51 nM-151 µM concentrations, on wound healing responses in immortalized human skin keratinocytes (HaCaTs). Both EBC-46 and EBC-211 (1.51 nM-15.1 µM) accelerated G0/G1-S and S-G2/M cell cycle transitions and HaCaT proliferation. EBC-46 (1.51-151 nM) and EBC-211 (1.51 nM-15.1 µM) further induced significant HaCaT migration and scratch wound repopulation. Stimulated migration/wound repopulation responses were even induced by EBC-46 (1.51 nM) and EBC-211 (1.51-151 nM) with proliferation inhibitor, mitomycin C (1 μM), suggesting that epoxy-tiglianes can promote migration and wound repopulation independently of proliferation. Expression profiling analyses showed that epoxy-tiglianes modulated keratin, DNA synthesis/replication, cell cycle/proliferation, motility/migration, differentiation, matrix metalloproteinase (MMP) and cytokine/chemokine gene expression, to facilitate enhanced responses. Although epoxy-tiglianes down-regulated established cytokine and chemokine agonists of keratinocyte proliferation and migration, enhanced HaCaT responses were demonstrated to be mediated via protein kinase C (PKC) phosphorylation and significantly abrogated by pan-PKC inhibitor, bisindolylmaleimide-1 (BIM-1, 1 μM). By identifying how epoxy-tiglianes stimulate keratinocyte healing responses and re-epithelialization in treated skin, our findings support the further development of this class of small molecules as potential therapeutics for other clinical situations associated with impaired re-epithelialization, such as non-healing skin wounds.

Abstract
Primary Sjögren's syndrome (pSS) is a chronic autoimmune disease that is characterized by mononuclear cell infiltration of exocrine glands. T-cells have been shown to play a central role in tissue destruction and regulation of B-cell activity and the production of autoantibodies typifying pSS. Despite the fact that dendritic cells (DCs) are candidate key players in the activation of T- and B-cells in pSS, their contribution has been under evaluated. This manuscript reviews current insights in DC biology and examines literature on the role of DCs in the immunopathology of primary Sjögren's syndrome, focusing on the interplay between dendritic cells, epithelial cells and T-cells.

Abstract
BACKGROUND The therapeutic effect of tonsillectomy for immunoglobulin A nephropathy (IgAN) has been widely recognized, but the mechanism by which tonsillar immunity leads to glomerulonephritis has been unclear. We investigated subtypes and localization of dendritic cells (DCs) in tonsils and looked for relationships between the tonsillar DCs and the clinical features and renal histological changes of patients with IgAN. METHODS We examined tonsils from 33 IgAN patients, using as control tonsillar specimens from subjects without glomerulonephritis. Five distinct markers of DCs (CD303, CD1c, CD209, CD208 and CD1a) were analyzed by immunohistochemistry and flow cytometry. The mRNA levels of these DC markers were evaluated using real-time polymerase chain reaction. The clinical data and histological results obtained evaluating renal biopsy tissues were statistically compared with immunological data. RESULTS Of the five subtypes of DCs, CD208(+) DCs were significantly increased in the tonsils of IgAN patients compared with that of controls. Furthermore, the number of CD208(+) DCs in the tonsils was positively and linearly correlated with the proportion of crescentic glomeruli in renal biopsy tissues and with the urinary protein level. Only few CD208(+) cells, however, were found in the kidney biopsy specimens of IgAN patients. CONCLUSIONS These observations suggest that increased CD208(+) DCs in tonsils may play a directive role in the pathogenesis of IgAN. The present results support the therapeutic significance of tonsillectomy for IgAN patients.

Abstract
OBJECTIVE Retrospective, observational study to explore the role of dendritic cells (DCs) in condyloma acuminatum lesions (genital warts) and their relationship with duration of the disease. METHODS Condyloma acuminatum lesion samples were collected from male patients with the condition and compared with normal foreskin samples from male volunteers. Cellular locations of dendritic cell lysosome-associated membrane protein (DC-LAMP) and dendritic cell-specific intercellular adhesion molecule-3 grabbing nonintegrin (DC-SIGN) were detected using immunohistochemistry. Levels of both proteins were determined using Western blot analysis; levels of their corresponding mRNAs were measured using reverse transcription-polymerase chain reaction. RESULTS The mRNA and protein levels of DC-LAMP and DC-SIGN were both significantly higher in condyloma acuminatum lesions (n = 30 samples) compared with normal skin samples (n = 13). Levels of DC-LAMP and DC-SIGN protein and duration of disease were inversely correlated. CONCLUSIONS DC-LAMP and DC-SIGN may be involved in the pathogenesis of condyloma acuminatum. Their levels were inversely correlated with the duration of disease, suggesting that DCs might be involved in human papillomavirus clearance.

Abstract
LAMP3/CD208 is a member of the lysosomal-associated membrane protein family and is used as a putative marker for mature dendritic cells (DCs) in humans since it is upregulated upon DC activation and maturation. This paper reports the cloning and sequencing of LAMP3 in rainbow trout. The predicted trout LAMP3 shares the characteristic features of LAMP family members such as a C-terminal lysosomal sorting motif (G-Y-D-R-I) in the short C-terminal cytoplasmic tail, typical for lysosomal targeting, four potential N-linked glycosylation sites (NXS/T), four conserved cysteines in the membrane-proximal domain and the luminal domain divided by a serine/proline-rich region. Expression studies revealed that trout LAMP3, like chicken LAMP3, was constitutively expressed in a wide range of lymphoid tissues, at highest levels in the head kidney, liver and spleen, respectively. LAMP3 was also constitutively expressed in trout head kidney macrophages and RTS11 cells and the expression was shown to be induced in vivo after infection with viral and bacterial pathogens and in cultured macrophages after modulation with microbial mimics (LPS and PolyIC). Thus, it is clear that if LAMP3 is expressed by trout DCs it is not exclusively expressed by them. However, the marker is valuable to further study antigen presentation in fish and to complement already known DC markers.

Abstract
OBJECTIVE To detect and compare the expression levels of two dendritic cell proteins, namely Dendritic Cell Lysosome-Associated Membrane Protein (DC-LAMP) and Dendritic Cell-Specific ICAM-3 Grabbing Non-integrin (DC-SIGN) in psoriasis vulgaris lesions and normal skin tissues. METHODS We used Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and immunohistochemical analysis to detect the expression of DC-LAMP and DC-SIGN in 33 samples representing plaque lesions of psoriasis vulgaris and 11 normal skin samples from healthy volunteers. RESULTS RT-PCR The expression levels of DC-LAMP and DC-SIGN were higher in samples of psoriasis vulgaris lesions than in that of normal skin, based on RT-PCR results.Whereas DC-LAMP staining was mostly cytoplasmic in keratinocytes of basal and spinous epidermis and dermal dendritic cells, DC-SIGN staining was both cytoplasmic and nuclear in keratinocytes of spinous epidermis and dermal dendritic cells. The expression levels of DC-LAMP and DC-SIGN proteins were significantly higher in psoriasis vulgaris lesions when compared with normal skin tissues (P<0.01). Furthermore, we found a positive correlation between high DC-LAMP and high DC-SIGN expression levels in psoriasis vulgaris lesions (P<0.05, r=0.368). CONCLUSION Compared with normal tissues, the levels of DC-LAMP and DC-SIGN were higher in psoriasis vulgaris lesions. Both DC-LAMP and DC-SIGN proteins may be involved in the pathogenesis of psoriasis vulgaris. The high expression of DC-LAMP may be associated with the altered differentiation of keratynocytes in psoriasis.
