Dysregulation in protein homeostasis results in accumulation of protein aggregates, which are sequestered into dedicated insoluble compartments so-called inclusion bodies or aggresomes, where they are scavenged through different mechanisms to reduce proteotoxicity. The protein aggregates can be selectively scavenged by macroautophagy/autophagy called aggrephagy, which is mediated by the autophagic receptor SQSTM1. In this study, we have identified PLK2 as an important regulator of SQSTM1-mediated aggregation of polyubiquitinated proteins.

IL-7 is a cytokine produced by stromal cells, which binds to IL-7Rα and plays an important role for homeostasis of T lymphocytes. Excessive activities of IL-7-triggered signaling pathways causes autoimmune diseases. How IL-7-triggered signaling and immune effects are regulated is not fully understood.

Article Synopsis
  • Psoriasis is a chronic autoimmune condition that affects the skin and significantly impacts the psychological and social well-being of patients and their families, yet research on the experiences of spouses is scarce.
  • The study aimed to understand the challenges and coping strategies of spouses dealing with the burden of psoriasis through in-depth interviews with fifteen participants, leading to the identification of key themes.
  • Findings revealed three main themes: an overwhelming disease burden, a lack of support systems, and various coping strategies, emphasizing the importance of healthcare providers addressing the needs of spouses while fostering effective coping mechanisms.

Background: Randomized controlled trials indicated guselkumab, the first anti-interleukin-23 monoclonal antibody, is efficacious in plaque psoriasis. However, guselkumab's performance in real life is scarcely examined, especially in China.

Objectives: This work aimed to assess the long-term effectiveness of guselkumab in actual clinical practice in China.

Ustekinumab is a biological therapy that has been approved for treating moderate-to-severe psoriasis. Although injection site reactions, nasopharyngitis, headaches, and infections are the common adverse events associated with ustekinumab, the development of bullous pemphigoid (BP) is also thought to be related to ustekinumab. Given that psoriasis itself can be complicated by BP, it is worthwhile to investigate the relationship between ustekinumab, psoriasis, and BP.

Interleukin-33 (IL-33) which belongs to the interleukin-1 (IL-1) family is an alarmin cytokine with critical roles in tissue homeostasis, pathogenic infection, inflammation, allergy and type 2 immunity. IL-33 transmits signals through its receptor IL-33R (also called ST2) which is expressed on the surface of T helper 2 (Th2) cells and group 2 innate lymphoid cells (ILC2s), thus inducing transcription of Th2-associated cytokine genes and host defense against pathogens. Moreover, the IL-33/IL-33R axis is also involved in development of multiple types of immune-related diseases.

Intricate associations between rhizosphere microbial communities and plants play a critical role in developing and maintaining of soil ecological functioning. Therefore, understanding the assembly patterns of rhizosphere microbes in different plants and their responses to environmental changes is of great ecological implications for dynamic habitats. In this study, a developing mid-channel bar was employed in the Yangtze River to explore the assembly processes of rhizosphere fungal communities among various plant species using high-throughput sequencing-based null model analysis.

Background: Little is known about different Ixekizumab (IXE) dosing regimens during routine clinical practice.

Objectives: To evaluate the real-world effectiveness and safety of different IXE dosing regimens in patients with psoriasis.

Materials & Methods: This study retrospectively compared patients who were dosed with IXE every two or four weeks (80 mg/week following a starting dose of 160 mg at Week 0).

Article Synopsis
  • This study aimed to compare the effectiveness of different biologic drugs for treating psoriasis over a 52-week period in real-world settings, addressing a lack of existing data.
  • A total of 386 patients using biologics like ixekizumab, secukinumab, guselkumab, and adalimumab were analyzed, revealing that guselkumab had the highest drug survival rate at 72.2%.
  • Findings indicate that improving drug efficacy is essential for enhancing treatment outcomes in psoriasis patients, as the main reasons for stopping treatment were lack of effectiveness and economic burdens.

Succession of microbial and plant communities is crucial for the development and the stability of soil ecological functions. The relative role of plant communities and environmental disturbance in shaping the microbial community in a newly established habitat remains unclear. In this study, a mid-channel bar (MCB) exposed to an environmental disturbance gradient in the Yangtze River was studied to explore the effects of such disturbance and plant community traits on the succession of the soil microbial community.

Understanding community assembly is a key issue in recognizing community succession and guiding the restoration of degraded ecosystems. Based on the stress-dominance hypothesis (SDH), along a gradient of increasing environmental stress, the relative importance of environmental filtering is supposed to be dominant but species interaction could be a minor process in assembling communities. However, this hypothesized model of the assembly-rule shift was equivocally supported by various studies.

The warning cytokine interleukin-33 receptor (IL-33R) mediates local inflammatory responses and plays crucial roles in the pathogenesis of immune diseases such as pulmonary fibrosis and rheumatoid arthritis. Whether and how IL-33R is regulated remain enigmatic. Here, we identified ubiquitin-specific protease 38 (USP38) as a negative regulator of IL-33R–mediated signaling.

Riparian ecosystem is structurally unstable due to the frequent disturbances from water fluctuation. Moreover, dams on large rivers tend to trigger fundamental changes of the composition and structure of riparian plant communities, which provides high odds for invasive species to colonize. Yet, how the invasive species distribute along a dam-induced riparian habitat, and how the native species resist to plant invasion are still puzzles.

Although there have been many epidemiological studies, research focusing on psoriasis' health burden on a global scale is still lacking. Trends and variations in the global health burden of psoriasis are evaluated by time, age, gender, geographical location, and socioeconomic status, using disability-adjusted life years (DALYs) from the Global Burden of Disease Study. The health burden of psoriasis was evaluated by DALYs, which combined years lost to disability (a morbidity component) with years of life lost (a mortality component).
