Summary

Cerebral infarction (CI) triggers significant changes in both humoral and cell-mediated immunity, including altered antibody levels and increased immune response indices. Antiphospholipid antibodies (aPLs) are identified as a key risk factor for stroke, particularly in younger individuals.

Area of Science:

  • Immunology
  • Neurology
  • Pathophysiology

Context:

  • Limited data exists on the immunological mechanisms underlying cerebral infarction (CI).
  • Understanding immune responses in CI is crucial for identifying risk factors and potential therapeutic targets.

Purpose:

  • To investigate humoral and cell-mediated immunity in patients with focal brain ischemia (CI).
  • To explore the role of antiphospholipid antibodies (aPLs) in stroke occurrence and recurrence.
  • To analyze the association of HLA antigens with CI.

Summary:

  • Patients with CI exhibited higher antibody levels against a panel of antigens compared to healthy controls, with significant increases in IgA and CSF immunoglobulins.
  • Cell-mediated immunity showed increased stimulatory (SI) and immunoregulatory (IRI) indices, particularly in younger stroke patients.

  • Anticardiolipin antibodies (aCLs), a type of aPL, were found in 9.8% of first-stroke patients, indicating a significant risk factor, especially for younger individuals and recurrent strokes.
  • Genetic factors, suggested by altered HLA antigen frequencies, may also contribute to CI onset.

    • Impact:

    • This study highlights the complex interplay between the immune system and cerebral infarction.
    • Identifies aPLs as a significant, potentially causal, risk factor for stroke, guiding future research and clinical management.
    • Suggests potential genetic predispositions to CI, warranting further investigation.
