Hypertension: Focus on autoimmunity and oxidative stress

Area of Science:

• Immunology
• Cardiovascular Medicine
• Nephrology

Background:

• Primary hypertension involves immune and inflammatory responses, mirroring autoimmune disease mechanisms.
• Autoimmune diseases like lupus and rheumatoid arthritis show a significantly higher prevalence of hypertension.

Purpose of the Study:

• To review clinical and epidemiological evidence linking hypertension and autoimmunity.
• To explore the underlying mechanisms, including inflammation, oxidative stress, and immune cell involvement.

Main Methods:

• Review of clinical and epidemiological data.
• Analysis of immunological and molecular mechanisms.
• Examination of therapeutic strategies targeting immune and oxidative pathways.

Main Results:

• A self-perpetuating cycle of inflammation and oxidative stress contributes to vascular dysfunction and renal damage in hypertension.
• Immune cell infiltration (T cells, B cells, macrophages, NK cells) is crucial for hypertensive pathology.
• Cytokines (IFN-γ, TNF-α, IL-17) and reactive oxygen species (NADPH oxidases) mediate renal and vascular effects.

Conclusions:

• Hypertension and autoimmunity are mechanistically linked through shared immune and inflammatory pathways.
• Targeting oxidative stress and immune responses presents promising therapeutic avenues for hypertension.
• Novel therapies focusing on neo-antigenic peptides and established immunosuppressive treatments are being investigated.
