Core Tip

Core Tip: This study pioneers Akkermansia muciniphila (A. muciniphila) intervention evaluation in streptozotocin-induced type 1 diabetes mellitus (T1DM) mice. Despite no reversal of hyperglycemia or islet damage after short-term (3-day) oral administration, A. muciniphila ameliorated immune imbalance by enhancing intestinal barrier function (increased zonula occludens-1, decreased zonulin), suppressing pro-inflammatory cytokines (tumor necrosis factor-alpha, interferon-gamma), increasing anti-inflammatory interleukin-4 and regulatory T cells, modulating signaling pathways (reduced signal transducer and activator of transcription 1, suppressed nuclear factor kappa-B p65), and decreasing intestinal Actinobacteria abundance. These findings highlight A. muciniphila’s potential for immune regulation in established T1DM by gut barrier repair and microbial shifts.
