Furthermore, elevated IL-8 in the T2DM cohort correlated with lower hippocampal A\u03b2 burden (p\u2009=\u20090.041) and attenuated atrophy rates in the parahippocampal cortex (p\u2009=\u20090.044). In contrast, no significant associations between IL-8 and any AD biomarkers or cognitive trajectories were observed in the non-T2DM group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This research demonstrates that the role of IL-8 in MCI is \u201ccontext-dependent,\u201d contingent upon the patient's metabolic state.
