Core Viewpoint - Targeted Protein Degradation (TPD) technologies, such as PROTAC, offer promising new avenues for drug development, but face challenges in degrading transmembrane proteins due to their reliance on degradation mechanisms that cannot access these proteins effectively [2][5]. Group 1: TPD Technologies and Challenges - Various TPD strategies have been developed for transmembrane proteins, including LYTAC, GlueTAC, and TransTAC, which open unprecedented research opportunities [2]. - These technologies depend on the Endosome-Lysosome pathway and are influenced by Recycling Endosomes, which tend to recycle transmembrane targets, thus reducing degradation efficiency [2]. - Most TPD strategies utilize large biomolecules like antibodies, while small molecule compounds may offer advantages such as easier delivery, lower costs, diverse application routes, longer shelf life, and typically non-immunogenic properties [2]. Group 2: ERADEC Development - A new TPD technology named ERADEC (ERAD-engaging Chimera) was developed by a research team from Fudan University and the Naval Medical University, which "hijacks" the ER-associated degradation (ERAD) mechanism to promote the ubiquitination and degradation of target proteins [3][6]. - The team discovered that the small molecule desonide can bind to the ER E3 ubiquitin ligase SYVN1, facilitating the ubiquitination and subsequent degradation of target proteins [6]. Group 3: Validation and Broader Implications - The ERADEC technology was validated using the PD-L1 protein, demonstrating efficient degradation through SYVN1 and ERAD dependency, outperforming widely used PD-L1 antibodies in tumor suppression effects in mouse models [7]. - The concept of ERADEC can be extended to other membrane proteins, indicating its potential as a universal platform technology for selective and efficient degradation of transmembrane proteins [9].

Core Viewpoint - The article discusses the characteristics, management strategies, and misconceptions related to eczema, emphasizing the need for tailored approaches based on different demographics and conditions. Group 1: Eczema Characteristics - Eczema presents with varying features depending on the disease stage: acute phase shows red papules with exudation, subacute phase shows darkening redness with scaling, and chronic phase shows thickened, leathery skin with pigmentation [2] - In infants, eczema commonly appears on exposed areas like cheeks and scalp, while in school-aged children, it is often found in flexural areas like the elbows and knees. In the elderly, it typically occurs on the lower legs and hands [2] Group 2: Management Strategies - For infants, a moisturizing strategy is crucial, with studies indicating that using moisturizers at least three times daily can reduce moderate to severe eczema flare-ups by 67% [3] - Medication principles for sensitive areas include using 1% pimecrolimus cream or 0.03% tacrolimus ointment, while mild steroids can be used for acute flare-ups on the body [3] - Elderly patients should use moisturizers containing urea (5%-10%) and avoid long-term use of potent steroids, opting instead for intermittent therapy [6] Group 3: Environmental Considerations - Maintaining a room temperature of 20-22 degrees Celsius and humidity of 50%-60% is recommended for eczema management [5] - Clothing for children should be made of pure cotton, and new clothes should be washed in hot water to remove residual chemicals [5] Group 4: Misconceptions and Risks - Traditional beliefs about "removing dampness and toxins" are challenged by modern medicine, which shows that excessive sweating can damage the skin barrier [7] - The fear of using corticosteroids is addressed, highlighting that when used correctly, the risk of skin atrophy is minimal [8] - Patients are advised against blindly avoiding foods unless a specific allergy is confirmed, and a diverse diet during pregnancy may reduce the risk of allergies in infants [10] Group 5: Importance of Individualized Management - Establishing a management model that focuses on moisturizing, medication to control flare-ups, and avoiding triggers is essential [11] - Keeping a diary to track triggers, medication use, and skin condition can aid healthcare providers in creating personalized treatment plans [11]
