Article Synopsis
  • Lung cancer (both non-small cell and small cell types) is currently treated with a mix of chemo- and immunotherapy, but effective biomarkers for predicting patient responses are needed.
  • The study focuses on the cGAS-STING pathway in peripheral blood mononuclear cells (PBMCs) to identify treatment responses in lung cancer patients, revealing that better responders had significantly higher levels of STING and CXCL10.
  • Results suggest that activating the cGAS-STING signaling in PBMCs could serve as a novel predictor for immunotherapy response, with higher levels indicating better treatment outcomes and enhanced anti-tumor immune activity.

Patients with early stage cutaneous T cell lymphoma (CTCL) usually have a benign and chronic disease course, characterized by temporally response to conventional skin directed therapies and intrinsic possibility to evolve. Using the combination of psoralen plus ultraviolet A irradiation (PUVA) and low-dose interferon-α (INF), the principal treatment goal is to keep confined the disease to the skin, preventing disease progression. Among 87 patients with early stage IA to IIA MF treated with low-dose IFN-α2b and PUVA in our center, complete remission (CR) were reported in 70 patients (80.

Objective: The aim of the survey was a retrospective analysis of a consistent number of iatrogenous and idiopathic SCLE cases, by means of clinical and histopathologic investigation.

Methods: Eleven European university dermatology units collected all diagnosed cases from January 2000 to December 2016.

Article Synopsis
  • Sp140 is a leukocyte-specific protein involved in immune response and regulation of gene transcription, particularly in macrophages, and has implications in blood cancers.
  • Through mass spectrometry and biochemical analysis, researchers identified multiple SUMOylation sites on Sp140, indicating it can undergo post-translational modifications that affect its function.
  • The PHD finger domain of Sp140 acts as a platform for protein interactions and facilitates SUMOylation of the adjacent BRD domain, suggesting that Sp140's structural features allow for complex regulatory roles beyond just binding to histones.

Amyotrophic lateral sclerosis (ALS) is a fatal neurological disorder that is characterized by a progressive degeneration of motor neurons (MNs). The pathomechanism underlying the disease is largely unknown, even though increasing evidence suggests that RNA metabolism, including microRNAs (miRNAs) may play an important role. In this study, human ALS induced pluripotent stem cells were differentiated into MN progenitors and their miRNA expression profiles were compared to those of healthy control cells.

The neutrophilic dermatoses (NDs) comprise a group of heterogeneous disorders characterized by inflammatory skin lesions that histologically show an intense inflammatory infiltrate composed primarily by neutrophils, with no evidence of infection or vasculitis. Although there are distinct clinical differences in the classical lesions of these disorders, many patients have overlapping features. In this review, we describe the clinical aspects of the main NDs, including: Sweet Syndrome, ND of the dorsal hands, pyoderma gangrenosum, erythema elevatum diutinum, subcorneal pustular dermatosis, neutrophilic eccrine hidradenitis, rheumatoid neutrophilic dermatitis, neutrophilic panniculitis, and aseptic abscesses including their association with underlying diseases and the differential diagnoses.

Background: Psoriasis is an inflammatory disease, that is increasingly being considered as a systemic disorder. Among associated comorbidities, metabolic syndrome plays an important role. The effects of biological therapies on metabolic syndrome is controversial.

The recognition of a melanocytic tumor as a melanoma is not based upon the search of single, objective and easily reproducible morphological diagnostic features but, instead, it stems from a constellation of diagnostic criteria whose implementation, meaning and relative weight vary considerably from one case to another. We have herein tried to summarize the most reliable criteria. In conclusion, the pathologist should provide the surgeon with a report containing sufficient information to allow an evidence-based patient management planning, and to permit an accurate indication of prognosis to be determined.

Background: Switching is a "hot" topic and the main reasons for switching prior biologic agent are for a primary failure, a secondary failure or drug intolerance, patient's dissatisfaction, physician decision. The aim of the study was to assess the optimization of the switching from a biologic agent to another.

Methods: Five Dermatological Units have participated to PsOMarche working group have studied thirty-eight patients affected moderate to severe chronic plaque psoriasis at time 0 (patient recruitment at time of switching from biological therapy to another), 8 weeks (T8), 16 weeks (T16).

Alternative splicing of terminal exons increases transcript and protein diversity. How physiological and pathological stimuli regulate the choice between alternative terminal exons is, however, largely unknown. Here, we show that Brahma (BRM), the ATPase subunit of the hSWI/SNF chromatin-remodeling complex interacts with BRCA1/BARD1, which ubiquitinates the 50 kDa subunit of the 3' end processing factor CstF.

Fused in sarcoma (FUS) is a ubiquitously expressed RNA-binding protein proposed to function in various RNA metabolic pathways, including transcription regulation, pre-mRNA splicing, RNA transport and microRNA processing. Mutations in the FUS gene were identified in patients with amyotrophic lateral sclerosis (ALS), but the pathomechanisms by which these mutations cause ALS are not known. Here, we show that FUS interacts with the minor spliceosome constituent U11 snRNP, binds preferentially to minor introns and directly regulates their removal.

Introduction: Bexarotene is a synthetic retinoid effective in early and advanced stages of mycosis fungoides (MF)/Sezary Syndrome (SS) both in monotherapy and combination schemes. We aimed to assess disease response to low-dose bexarotene and PUVA in maintenance in refractory and/or resistant patients with early and advanced stage MF/SS.

Methods: We followed prospectively 21 patients (stages IB-IV): 15 with early stage MF and 6 with advanced disease.

Actinic keratoses (AKs) are the most common keratinocytederived precancerous lesion in humans; they can be observed predominantly in fair-skinned individuals on sun-exposed surfaces. The primary risk factor for AKs is cumulative UV exposure from sunlight and/or tanning salons. AKs may present on a patient as a few detectable lesions.

Background: STRATOS is the acronym of the "STRuctured Approach to the Treatment of psOriatic patientS". The optimization of the psoriasis's therapeutic management is one of the most important goals for dermatologists. According to Mrowietz's consensus report, the transitioning from conventional therapy to biological therapy is mainly due to the lack/loss of efficacy and/or for safety reasons.

Cutaneous vasculitis comprises a wide spectrum of diseases that involve predominantly the blood vessels and surrounding tissues of the skin. Few vasculitic syndromes have pathognomonic clinical, radiographic and/or laboratory findings; thus, confident and accurate diagnosis of vasculitis requires histological confirmation. Skin biopsy should be done, optimally within 24 to 48 hours after vasculitic lesions appear.

Background: The pathogenesis of psoriasis is complex, with a significant role suggested for pro-inflammatory mediators. There is strong evidence of an association between psoriasis and the metabolic syndrome (MetS), a cluster of cardiovascular risk factors, which impose a substantial disease burden.

Objective: This study aimed to evaluate the prevalence of MetS and to examine the implications of disease severity, type 2 diabetes mellitus, and cardiovascular disease in a large cohort of Italian psoriatic patients representative of the whole population.

SUMOylation is a protein posttranslational modification that participates in the regulation of numerous biological processes within the cells. Small ubiquitin-like modifier (SUMO) proteins are members of the ubiquitin-like protein family and, similarly to ubiquitin, are covalently linked to a lysine residue on a target protein via a multi-enzymatic cascade. To assess the specific mechanism triggered by SUMOylation, the identification of SUMO protein substrates and of the precise acceptor site to which SUMO is bound is of critical relevance.
