Background: The Cluster of Differentiation 27 (CD27) is aberrantly expressed in multiple myeloma (MM) -derived. This expression facilitates the interaction between tumor and immune cells within TME via the CD27-CD70 pathway, resulting in immune evasion and subsequent tumor progression. The objective of this study is to investigate the correlation between CD27 expression and the prognosis of MM, and to elucidate its potential relationship with the immune microenvironment.
Methods: In this research, CD27 expression in T cells within the 82 newly diagnosed MM microenvironment was assessed via flow cytometry. We then examined the association between CD27 expression levels and patient survival. Subsequent a series of bioinformatics and in vitro experiments were conducted to reveal the role of CD27 in MM.
Results: Clinical evidence suggests that elevated CD27 expression in T cells within the bone marrow serves as a negative prognostic marker for MM survival. Data analysis from the GEO database has demonstrated a strong association between MM-derived CD27 and the immune response, as well as the hematopoietic system. Importantly, patients with elevated levels of CD27 expression were also found to have an increased presence of MDSCs and macrophages in the bone marrow microenvironment. Furthermore, the PERK-ATF4 signaling pathway has been implicated in mediating the effects of CD27 in MM.
Conclusions: We revealed that CD27 expression levels serve as an indicative marker for the prognosis of MM patients. The CD27- PERK-ATF4 is a promising target for the treatment of MM.

Objective: To explore the characteristics of the immunophenotypic expression of bone marrow monocytes (M) and its clinical significance in patients with multiple myeloma (MM).
Methods: The monocyte immunophenotypes expression of 67 MM and 30 anemic patients (control group) were detected by flow cytometry. The immunophenotypes that exhibited statistical differences from the control group were screened out.

Objective: To elucidate the association between the changes in intracellular metabolism in the early stage of B cell activation and systemic lupus erythematosus (SLE) pathogenesis.
Methods: CD19 or CD19CD27 (naïve) cells from the peripheral blood of healthy controls and lupus patients were cultured under different stimuli. The changes in intracellular metabolism and signalling pathways in these cells were evaluated.

Objective: Nephrotic syndrome, a debilitating manifestation of kidney disease, often arises from diverse glomerular disorders and is accompanied by notable comorbidities. Despite indications of an immunological etiology, the precise role of immune cells in its pathogenesis remains unclear. This study aimed to elucidate the causal relationships between circulating immune cell phenotypes and nephrotic syndrome using a rigorous bidirectional Mendelian randomization approach.

Purpose: This study aimed to elucidate the role of polymeric immunoglobulin receptor (pIgR) autoantibodies in the pathogenic progression of biliary atresia (BA).
Methods: The presence and levels of plasma pIgR autoantibodies, pIgR antigen expression, and B cell counts were assessed in liver tissues. Serum extracellular vesicles (EVs) were isolated, quantified, and characterized.

Long-term control of viral replication relies on the efficient differentiation of memory T cells into effector T cells during secondary immune responses. Recent findings have identified T cell precursors for both memory and exhausted T cells, suggesting the existence of progenitor-like effector T cells. These cells can persist without antigenic challenge but expand and acquire effector functions upon recall immune responses.
