Summary: Macroautophagy/autophagy is a cellular process responsible for eliminating and recycling aggregated proteins and damaged organelles. The compartmentalization of PRKA/PKA determines its effects on autophagy, with increased cAMP levels generating different PRKA activity signatures. The distribution of PRKA holoenzymes plays a role in affecting the autophagic flux in specific cell types.

Summary: AMP-activated protein kinase (AMPK) plays a central role in maintaining energy homeostasis by regulating signaling input and metabolic pathways. Its subcellular compartmentalization is crucial for accessing proper targets and generating appropriate responses to various stressors. Tissue-specific distribution and nucleo-cytoplasmic shuttling are influenced by factors such as starvation, exercise, and heat shock, highlighting the importance of AMPK localization in coordinating signaling and metabolism.

Summary: Hypoxia is crucial for the development of various disorders, especially hypoxic cerebropathy. The damage to the blood-brain barrier (BBB) caused by hypoxia is well known. This study explored the correlation between endothelial ferroptosis and hypoxia-induced BBB damage using in vivo zebrafish and in vitro bEnd.3 cells. The results showed that hypoxic treatment could induce BBB disruption by down-regulating claudin-5 (CLDN5) expression in both zebrafish cerebrovascular endothelial cells and bEnd.3 cells.

Summary: This study successfully increased the efficiency of cellulose acid production from 7.36 g L-1 (native microbial consortium) to 57.57 g L-1 by re-assembling a simplified microbial consortium consisting of lignocellulose degrader Trichoderma asperellum and lactic acid (LA) producer Lactobacillus paracasei. The analysis of interactions between these two members provides insights for the construction of synthetic microbial consortia for the synthesis of other chemicals.

Summary: This study reveals the critical role of SerpinB7 in the regulation of keratinocyte differentiation and psoriatic microenvironment mediated via keratinocytes' intracellular calcium flux. SerpinB7 deficiency leads to excessive proliferation and impaired differentiation of keratinocytes, as well as increased expression of chemokines and antimicrobial peptides. The deficiency of SerpinB7 affects keratinocyte differentiation and proinflammatory cytokines possibly by affecting calcium ion channel-related proteins. These findings propose SerpinB7 as a potential therapeutic target for psoriasis.

Summary: “The study demonstrates that HIF alpha plays a key role in regulating thermogenic function in response to cold and re-warming. Specifically, HIF2 alpha suppresses PKA activity by inducing miR-3085-3p expression, leading to downregulation of PKA C alpha. Ablation of adipocyte HIF2 alpha stimulates retention of beige adipocytes during re-warming after cold stimuli. Moreover, administration of miR-3085-3p promotes beige-to-white transition via downregulation of PKA C alpha and mitochondrial abundance in adipocyte HIF2 alpha deficient mice. These findings highlight the importance of HIF2 alpha-dependent PKA regulation in dynamic remodeling of beige adipocytes as thermostats.”

Summary: This study characterizes the regulation of IL-17A and IL-17F in psoriatic disease, showing that IL-17F is elevated preferentially over IL-17A and that each isoform is expressed in distinct cell populations. The study also reveals the plasticity of IL-17A and IL-17F expression, influenced by proinflammatory signaling and anti-inflammatory drugs. Higher IL-17F expression is linked to increased cell proliferation, suggesting the importance of neutralizing both IL-17A and IL-17F in inhibiting IL-17-driven pathology.

Summary: The study in BALB/c mice model revealed that CVA2 infection induced lung damage by significantly increasing lung microvascular permeability, infecting lung endothelial cells, promoting apoptosis, and disrupting tight junctions. The infection also led to degradation of tight junction proteins, upregulation of genes related to endothelial dysfunction, activation of inflammatory cytokines, and p38-MAPK signaling pathways. Targeting p38-MAPK signaling may offer a therapeutic strategy for pulmonary edema in critical HFMD infections.

Summary: The study found that exogenous glutathione reduces cadmium accumulation in roots by up-regulating BOT1/2 expression, promoting PC synthesis, and enhancing the expression of BcABCC1/2, all of which contribute to the compartmentalization of Cd in root vacuoles in pakchoi under Cd stress.

Summary: This study found increased CD8+ and perforin+ cells in the lesions of vitiligo patients. The expression levels of perforin were elevated in the CD8+ T cells from peripheral blood of vitiligo patients and their culture supernatants. The perforin promoter was hypomethylated in vitiligo CD8+ T cells. Treatment with the DNA methylation inhibitor 5-Azacytidine reduced the perforin methylation level and caused perforin overexpression.

Summary: In this study, the researchers found that the WFDC12 gene plays a role in the pathogenesis of atopic dermatitis (AD). They discovered that WFDC12 is highly expressed in the skin tissue and lesions of AD patients. By overexpressing WFDC12 in the epidermis of transgenic mice, they observed increased migration of skin-presenting cells, enhanced Th cell infiltration, and upregulation of immune cells and cytokines. They also found that WFDC12 promotes arachidonic acid metabolism and platelet-activating factor (PAF) accumulation, exacerbating AD-like symptoms.

Summary: The loss of actin-binding protein alpha-adducin reduces desmosome numbers and impairs the ability of keratinocytes or epidermis to withstand mechanical stress. This is not mainly due to decreased levels or impaired adhesive properties, but rather altered turnover of desmosomal molecules.

Summary: This study successfully induced a cardiac phenotype in mice that met the diagnostic criteria for ACM by causing defects in intercellular adhesion of cardiac cells through mutation. It confirmed integrin-alpha V beta 6 and transforming growth factor-beta signaling as key pathways leading to fibrosis. Blocking this pathway reduced fibrotic markers expression and fibrosis formation, offering a promising target for treating ACM.

Summary: The study demonstrates that an antibody called 2G4 can induce weakened intercellular keratinocyte adhesion and activate the p38MAPK signal transduction pathway, leading to a severe autoimmune skin disease called pemphigus vulgaris. This study provides further insights into the underlying mechanisms of desmosomal keratinocyte adhesion and blister formation in pemphigus vulgaris.

Summary: Desmoglein 3 (Dsg3) is a cadherin protein that mediates cell adhesion and is the antigen of pemphigus vulgaris. Using super resolution microscopy, researchers studied the cytoskeletal anchorage of Dsg3 on living keratinocytes and discovered the existence of two pools of Dsg3 with different anchorage mechanisms. These findings provide valuable insights into cell adhesion and keratinocyte formation.

Summary: Desmosome diseases are caused by dysfunction of desmosomes, which anchor intermediate filaments (IFs) at sites of cell-cell adhesion. The understanding of the role of desmosomes has shifted from the focus on actin filament-associated adherens junctions to the interference with desmosome function and its molecular constituents. The Alpine desmosome disease meeting provided a platform for researchers and clinical experts to discuss the function and dysfunction of desmosomes in different cell types and their involvement in various diseases.
