Insights

Immunoglobulin A nephropathy (IgAN) patients show altered cellular immunity, with increased CD4+ and CD25+ cells. Interleukin-2 (IL-2) levels in stimulated cells suggest a key role in T-cell activation for IgAN.

Area of Science:

  • Immunology
  • Nephrology
  • Cellular Biology

Background:

  • Immunoglobulin A nephropathy (IgAN) is a common glomerular disease.
  • Cellular immunity alterations are implicated in IgAN pathogenesis.
  • Understanding immune responses in IgAN is crucial for therapeutic development.

Purpose of the Study:

  • To investigate cellular immunity changes in patients with IgAN.
  • To assess the role of specific immune cells and cytokines in IgAN.
  • To explore correlations between immune markers and clinical parameters in IgAN.

Main Methods:

  • Analysis of cellular immunity in 24 IgAN patients and controls.
  • Quantification of CD4+ and CD25+ cell populations.
  • Measurement of serum and stimulated peripheral blood mononuclear cell (PBMC) cytokine levels (IL-2, IL-4).

Main Results:

  • Increased CD4+ and CD25+ cells were observed in IgAN patients compared to controls.
  • Serum IL-2 and IL-4 levels were similar between groups.
  • Higher IL-2 levels were found in stimulated PBMC supernatants from IgAN patients.
  • No significant correlations were found between immune markers and renal function, IgA levels, or urinary findings.

Conclusions:

  • The study suggests a significant role for IL-2 in T-cell activation within the cellular immune response in IgAN.
  • Elevated IL-2 in stimulated cells indicates a potential mechanism contributing to IgAN.
  • Further research into IL-2's role may offer new therapeutic targets for IgAN.

Overview
Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...
T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
