Objective: Immune-related pancytopenia (IRP) is characterized by autoantibody-mediated destruction or suppression of bone marrow cells, leading to pancytopenia. This study aimed to explore the role of TRAPPC4 (trafficking protein particle complex subunit 4) as a key autoantigen in IRP, including epitope identification and immune activation mechanisms.
Methods: A total of 90 participants were included in the study, divided into four groups: 30 newly diagnosed IRP patients, 25 IRP remission patients, 20 patients with control hematologic conditions (severe aplastic anemia [SAA] and myelodysplastic syndrome [MDS]), and 15 healthy controls.

The dysfunction of the endothelial lining in lesion-prone areas of the arterial vasculature significantly contributes to the pathobiology of atherosclerotic cardiovascular disease. Recent studies suggested that UDP-glucose pyrophosphorylase 2 (UGP2) plays a role in cell proliferation and survival. This study investigates the anti-apoptotic and anti-atherogenic effects of UGP2 both in vitro and in vivo.

Background: ARPC1B has been identified as a key regulator of malignant biological behavior in various tumors. However, its specific role in clear cell renal cell carcinoma (ccRCC) remains poorly understood. This study aims to evaluate the influence of ARPC1B on the prognosis and disease progression in ccRCC patients.

Background: Systemic Lupus Erythematosus (SLE) is a typical autoimmune disease characterized by a complex pathogenesis and a strong genetic predisposition. The study of inflammatory response in SLE monocytes is not very clear, and exploring the inflammatory factors of monocytes is beneficial to discover new diagnostic targets.
Results: Using scRNA-seq technology, we obtained the quantitative changes in circulating immune cells and various cellular immune metabolic profiles between SLE patients and healthy volunteers.
