Insights

Aberrant immune cell signaling contributes to cardiovascular disease (CVD) and chronic kidney disease (CKD). This review explores the role of lymphocytes, including regulatory T cells (Tregs) and B cells, in CKD-related heart dysfunction.

Area of Science:

  • Immunology
  • Nephrology
  • Cardiology

Background:

  • Acquired immune system dysregulation is linked to cardiovascular disease (CVD) and chronic kidney disease (CKD).
  • Understanding lymphocyte abnormalities in CKD is crucial for elucidating their role in uremic cardiomyopathy.
  • T cell subsets show varied associations with myocardial function in CKD models.

Purpose of the Study:

  • To review current evidence on the role of acquired immune cells in the pathogenesis of myocardial structural and functional alterations in CKD.
  • To examine the involvement of T cell subsets, regulatory T cells (Tregs), and B lymphocytes in CKD-associated cardiac remodeling.

Main Methods:

  • Literature review of experimental and clinical studies.
  • Analysis of data on T cell subsets, Tregs, and B lymphocytes in CKD and CVD.
  • Synthesis of evidence regarding immune cell involvement in myocardial remodeling.

Main Results:

  • T cell subsets exhibit diverse associations with myocardial function in CKD.
  • Regulatory T cells (Tregs) may shift towards a profibrotic phenotype in CKD and heart failure.
  • B lymphocyte depletion is common in CKD and heart failure, but their direct role in myocardial damage is unclear.

Conclusions:

  • Acquired immune cells, particularly T cells and Tregs, play a significant role in the pathogenesis of myocardial alterations in CKD.
  • Further research is needed to clarify the specific mechanisms by which B lymphocytes contribute to cardiac damage in CKD.
  • Targeting immune pathways may offer therapeutic strategies for managing cardiorenal syndrome.

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Chronic Kidney Disease IV: Nursing Management

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
