Perspektywa porównawcza: Progranulin versus Other Inflammatory Biomarkers

Biomarker Primary Source Association with Diabetes Strengths Limitations
Progranulin Adipocytes, macrophages Strong with insulin resistance, complications Direct link to adipocyte inflammation; dual (pro‑/anti‑) regulatory role Assay variability; cleavage products complicate interpretation
hs‑CRP Liver (IL‑6 driven) Moderate with cardiovascular risk Standardized assay; widely available; low cost Non‑specific; not mechanistically tied to insulin signaling
IL‑6 Immune cells, adipose Strong with insulin resistance Key driver of acute phase response High diurnal variability; short half‑life
TNF‑α Macrophages, adipocytes Strong with insulin resistance Direct role in insulin receptor desensitization Unstable in blood; low circulating levels
Adiponectin Adipocytes Inverse with insulin resistance Anti‑inflammatory; well‑studied Negative correlation complicates interpretation
