Topical glucocorticosteroids inhibit allergic skin inflammation but are ineffective in impeding the formation and expansion of resident memory T cells

ABSTRACT: Tissue-resident memory T (TRM) cells are detrimental in numerous chronic inflammatory diseases, including allergic contact dermatitis (ACD), in which they contribute to the chronicity and severity of the disease. We assessed the impact of a standard glucocorticosteroid treatment, triamcinolone acetonide (TA), on the formation, maintenance and reactivation of epidermal TRM cells in ACD.

RNA-seq of synovial membranes from a preclinical model of post-traumatic knee osteoarthritis to evaluate the effects of corticosteroid treatment

Project description:Yorkshire pigs received untreated unilateral ACL transection through a medial arthrotomy (INJ, n=6), transection with immediate injection of 20mg triamcinolone acetonide (TRI, n=6) or no surgery (CON, n=6). Synovial membranes were harvested two weeks after the injury in the lateral knee joint compartment. The whole biopsy was homogenised for RNA extraction. The objective of the experiment was to test if intraarticular corticosteroid injection mitigates injury-induced synovitis and collagen degradation after anterior cruciate ligament transection and to characterize the synovial response using the described perturbations in combination with a functional genomics approach.

Distinct immune responses and pruritic mechanisms in oxazolone- and urushiol- induced ACD (Allergic contact dermatitis) models.

Project description:The mechanisms underlying pruritus and skin inflammation of poison ivy ACD remain poorly understood,due to limited clinical data and animal studies. Most of the mechanistic understanding of ACD is based upon animal models using experimental allergens not present in the environment, such as oxazolone,DNFB or SADBE . Recently, it has become evident that different allergens elicit widely divergent immune responses in both human and animals, suggesting these models may not be representative of environmental forms of ACD . Given the high incidence and public health impact of poison ivy-induced ACD, it is necessary to establish and characterize a clinically relevant animal model using the actual allergen urushiol. In this study we applied transcriptome microarray to evaluate the cutaneous immune response in urushiol ACD model.

In vivo Gene Expression Profiling of RPE/choroid Post-Intravitreal Injections of Dexamethasone and Triamcinolone at Clinically Relevant Time Points for Patient Care

Project description:PURPOSE To identify retinal pigment epithelial (RPE)/choroid genes and their relevant expression pathways affected by intravitreal injections of dexamethasone and triamcinolone acetonide in mice at clinically relevant time points for patient care. METHODS Differential gene expression of over 34,000 well-characterized mouse genes, in the RPE/choroid of 6 week old C57BL/6J mice were analyzed after intravitreal steroid injections at 1 week and 1 month post injection, using Affymetrix Mouse Genome 430 2.0 microarrays. The data were analyzed using GeneSpringGX12.5 and Ingenuity Pathway Analysis (IPA) microarray analysis software for biologically relevant changes. RESULTS Both triamcinolone and dexamethasone caused differential activation of genes involved in âCircadian Rhythm Signalingâ pathway at both time points tested. Triamcinolone (TAA) uniquely induced significant changes in gene expression in âCalcium Signalingâ (1 week) and âGlutamate Signalingâ pathways (1month). In contrast, Dexamethasone (Dex) affected the âGABA Receptor Signalingâ (1 week) and âSerotonin Receptor Signalingâ (1month) pathways. CONCLUSIONS Understanding how intraocular steroids affect the gene expression of RPE/choroid is clinically relevant. This in vivo study has elucidated several genes and pathways that are potentially altering the circadian rhythms and several other neurotransmitter pathways in RPE/choroid cells during intravitreal steroid injections, which likely has consequences in the dysregulation of RPE function and neurodegeneration of the retina. Total of 18 RPE/choroid samples were analysed. There were two time points, day7 and day30. Each time point had three groups: BSS control, DEX treatment and TAA treatment. Each group had three biological replicas.

Molecular analysis in SADBE-induced ACD (Allergic contact dermatitis) model

Project description:The mechanisms underlying pruritus of SADBE induced ACD (Allergic contact dermatitis) remain poorly understood,due to limited clinical data and animal studies. In this study, we investigated whether there are certain key signaling molecules downstream of the recently identified peptides mediating itch in the spinal cord. We investigated the changes in the trascriptome by performing RNAseq of cervical spinal cords in control and SADBE induced ACD model. Our study represents the detailed analysis of transcriptomes of spinal cord in chronic itch model with biologic replicates, generated by RNA-seq technology.

Long noncoding RNA (lncRNA) expression profiles of hypertrophic scar fibroblasts treated with glucocorticoids under mechanical stretch environment

Project description:After disruption of the skin, fibroblasts along wound edges are constantly exposed to high levels of stress, resulting in increased collagen synthesis and decreased apoptosis. Emerge evidences shows that, the hypertrophic scars tissue fibrosis phenomena are original from the intrinsic cellular mechanical stretch. Traditional glucocorticoids on hypertrophic scarring have been performed for 30 years, utilizing for their anti-inflammatory, anti-allergenic and immunomodulatory effects and for their well-established, pro-apoptotic effects on hematological malignancies. To explore effects of glucocorticoid triamcinolone acetonide (TA) for responses to mechanical stress in hypertrophic scars fibroblasts (HSFB), we performed microarrays to explore long noncoding RNA expression.
