Article Synopsis
  • - Chronic urticaria (CU) is linked to atopy, indicated by IgE sensitization, but specific information on its characteristics in CU is limited.
  • - An analysis of 1149 patients revealed 33.1% of CU patients had positive specific IgE and 49.0% had elevated total IgE, showing higher rates than healthy controls but lower than classic allergic diseases.
  • - The findings suggest CU patients have a distinct IgE sensitization profile that differs from traditional allergic diseases, highlighting the need for further research into its underlying causes and clinical implications.

Background: The inconsistency between serum total IgE (tIgE) and allergen-specific IgE (sIgE) results is often encountered in clinical practice, but the distribution and influencing factors of the inconsistent results have not been fully understood.

Objective: The aim of this study was to analyze the distribution and inconsistency between tIgE and sIgE test results.

Methods: A retrospective study, from the electronic medical records of 2139 patients who underwent both tIgE and sIgE tests, from January to December 2023 was reviewed.

Intrahepatic cholangiocarcinoma (ICC) is a universally lethal malignancy with increasing incidence. However, ICC patients receive limited benefits from current drugs; therefore, we must urgently explore new drugs for treating ICC. Quinolizidine alkaloids, as essential active ingredients extracted from , can suppress cancer cell growth via numerous mechanisms and have therapeutic effects on liver-related diseases.

Background: Systemic Lupus Erythematosus (SLE), a prototypical autoimmune disorder, presents a challenge due to the absence of reliable biomarkers for discerning organ-specific damage within SLE. A growing body of evidence underscores the pivotal involvement of N6-methyladenosine (m6A) in the etiology of autoimmune conditions.

Methods: The datasets, which primarily encompassed the expression profiles of m6A regulatory genes, were retrieved from the Gene Expression Omnibus (GEO) repository.

Objectives: To investigate the evidence of ferroptosis in peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE).

Methods: PBMCs were collected from 30 patients diagnosed as SLE and without any standardised treatment previously and 10 healthy controls. Meanwhile the clinical and laboratory data were collected.

Background: Circular RNAs are involved in autoimmune disease pathogenesis. Our previous study indicated that circPTPN22 is involved in autoimmune diseases, such as systemic lupus erythematosus (SLE) and rheumatoid arthritis, but the underlying mechanisms remain unclear.

Methods: First, the expression of circPTPN22 was detected by real-time PCR and western blotting.

Background: Coronavirus disease 2019 (COVID-19) shares similar immune characteristics with autoimmune diseases like systemic lupus erythematosus (SLE). However, such associations have not yet been investigated at the single-cell level.

Methods: We integrated and analyzed RNA sequencing results from different patients and normal controls from the GEO database and identified subsets of immune cells that might involve in the pathogenesis of SLE and COVID- 19.

Introduction: Allergen-specific IgE (sIgE) sensitization exists in a considerable fraction of chronic spontaneous urticaria (CSU) patients. Basophils have been implicated in the pathogenesis of CSU. This paper aimed to explore the relationship between allergic sensitization and basophil reactivity in CSU and the possible underlying mechanism.

Abnormal levels of SO in organisms can cause cardiovascular disease and respiratory allergies. In addition, the amount of SO derivatives used as food preservatives is strictly controlled, and excessive addition can also be harmful to health. Therefore, it is essential to develop a highly sensitive method for the detection of SO and its derivatives in biological systems and real food samples.

Latent HIV is a key factor that makes AIDS difficult to cure. Highly effective and specific latent HIV activators can effectively activate latent HIV, and then combined with antiretroviral therapy to achieve a functional cure of AIDS. Here, four sesquiterpenes (-) including a new one (), five flavonoids (-) including three biflavonoid structures, and two lignans ( and ) were obtained from the roots of Their structures were elucidated through comprehensive spectroscopic analyses.

Little is known about the association between coronavirus disease 2019 (COVID-19) and autoimmune diseases, especially in the case of systemic lupus erythematosus (SLE). SLE patients met with many questions during the pandemic in COVID-19, such as how to minimize risk of infection, the complex pathological features and cytokine profiles, diagnosis and treatment, rational choice of drugs and vaccine, good nursing, psychological supervision, and so on. In this study, we review and discuss the multifaceted effects of the COVID-19 pandemic on patients living with SLE using the available literature.

Ulcerative colitis (UC) is a chronic, relapsing, and nonspecific inflammatory bowel disease (IBD). Phillygenin (PHI), a natural bioactive ingredient, isolated from , exhibits anti-inflammatory, anti-oxidative, and hepatoprotective activities. However, few reports provide direct evidence on the efficacy of PHI in improving colitis mice.

The visualization of cell membrane and mitochondrial behavior in living cells is of great life science value, but challenging due to the lack of ideal probes. In this work, two novel fluorescent probes based on different lengths of alkyl chains were reported for selective targeting of cell membranes or mitochondria of living cells. The probe CTM (1-Octadecyl-4-[9-ethyl-6-(diphenylamino)-9H-carbazol-3-yl] pyridinium) achieved cell membrane-specific staining in cells.

Background: Plasmacytoid dendritic cells (pDCs) are the main producers of type I interferon (IFN-I), and the excessive production of IFN-I is a hallmark of systemic lupus erythematosus (SLE). Both SLC15A4 and miR-31-5p are SLE susceptibility-related genes, and SLC15A4 has been implicated an important role in endolysosomal toll-like receptor (TLR) activation in pDCs. However, whether miR-31-5p exerts a regulating effect on SLC15A4 expression in pDCs is unclear.

The discovery of efficient and specific HIV-latency-reversing agents is critical for HIV therapy. Here, we developed wikstroelide E, a daphnane diterpene from the buds of , as a potential HIV-latency-reversing agent that is 2500-fold more potent than the drug prostratin. Based on transcriptome analysis, the underlying mechanism was that wikstroelide E regulated the MAPK, PI3K-Akt, JAK-Stat, TNF, and NF-κB signaling pathways.
