Abstract Chemokines play critical roles in the recruitment and activation of immune cells both homeostatic pathologic conditions. Here, we examined chemokine ligand-receptor pairs to better understand immunopathogenesis cutaneous lupus erythematosus (CLE), a complex autoimmune connective tissue disorder. We used suction blister biopsies measure cellular infiltrates with spectral flow cytometry interface dermatitis reaction, as well 184 protein analytes interstitial skin fluid using Olink targeted proteomics. Flow data concordantly demonstrated significant increases T antigen presenting (APCs). also performed spatial transcriptomics proteomics punch digital profiling (DSP) technology on CLE healthy margin controls examine discreet locations within tissue. Spatial confirmed elevation interferon (IFN) IFN-inducible CXCR3 ligands. Comparing involved versus uninvolved keratinocytes samples revealed upregulation essential inflammatory response genes areas near dermatitis, including AIM2 .

Glucagon-like peptide-1 (GLP-1) is a hormone that regulates blood glucose levels and produced by the enteroendocrine glands in large small intestines response to consumption of foods contain carbohydrates, fats, proteins. When GLP-1 secreted, it acts on pancreas increase insulin production secretion, while decreasing pancreatic glucagon secretion order lower serum glucose. However, also metabolism through gut-brain axis. While primarily gut released into bloodstream, quantities can be synthesized distinct areas neurons located hindbrain. Recent studies have proposed receptor (GLP-1R) agonists (GLP-1RAs) may protect against neuroinflammatory diseases. GLP-1RAs therapeutic target for asthma as animal models show these drugs reduce allergen-induced airway inflammation, GLP-1R expressed lung epithelial endothelial cells. There notable association between resistance onset asthma, particularly among obese people, with this suggesting metabolic dysfunction play role development. evidence there link pathobiology neuroinflammation, its analogs regulate pathways contribute pathogenesis. Interest growing, though research remains limited, how inflammation nervous system might linked.

Thymus and activation-regulated chemokine (TARC; CCL17) is a T-helper-2 that reflects atopic dermatitis (AD) disease activity. Since 2008, serum TARC levels have been commercially measured in Japan, clinical experience has shown the usefulness of TARC. The fallacy eczema always visible often hinders successful treatment, when there subclinical inflammation which inferable from level. AD treatment entered new era with higher therapeutic efficacy. different meaning than it did previously, its significance limitations are discussed. First, more appropriate topical therapy monitoring would be useful selecting truly necessitated patients for expensive therapies. Dupilumab quickly lowers before improvement, normalization not criterion dose reduction. However, some severe cases, may help determine whether to continue treatment. During JAK inhibitors, elevated abnormally high, leading exacerbation dermatitis. Prurigo nodularis divided into two types associated normal levels, aid selection agents. In this era, remains biomarker accurate drug determination efficacy; Currently, trials AD, all outcome measurements depend on score; however use biomarker, such as TARC, secondary measure will clarify characteristics each pathophysiological conditions expected effective.

The epithelial barrier in different organs is the first line of defense against environmental insults and allergens, with type 2 immunity serving as a protective function. Genetic factors, biological chemical from surrounding environment altered regulate homeostasis through disruption tight junction proteins or dilated intercellular spaces. Recent studies suggest that dysfunction contributes to pathologic alteration diseases immune dysregulation including (but not limited to) atopic dermatitis, prurigo nodularis, asthma, chronic rhinosinusitis nasal polyps, eosinophilic esophagitis.

The prevalence rate of allergic rhinitis (AR) is high worldwide. inhalation allergens induces AR, which an immunoglobulin E-mediated and type 2 inflammation-driven disease. Recently, the role neuroimmune communication in AR pathogenesis has piqued interest scientific community. Various neuropeptides, such as substance P (SP), vasoactive intestinal peptide (VIP), calcitonin gene-related (CGRP), nerve growth factor (NGF), neuromedin U (NMU), released via “axon reflexes” or “central sensitization” exert regulatory effects on immune cells to elicit “neurogenic inflammation,” contributes nasal hyperresponsiveness (NHR) AR. Additionally, neuropeptides can be produced cells. frequent colocalization neuronal at certain anatomical regions promotes establishment cell units, nerve-mast cells, nerve-type innate lymphoid (ILC2s), nerve-eosinophils nerve-basophils units.
