Mechanisms Linking Maternal Diet to Offspring Autoimmunome Risk

Understanding how maternal nutrition influences autoimmune risk requires examining epigenetic, microbial, and immunological pathways in greater depth. These mechanisms often interact—for example, epigenetic changes affect gut barrier function, and the microbiome influences immune cell development through short-chain fatty acids.

Amentinal diet can alter the epigenome of thee fetus the the them think changes in DNA methylation, histone modifications, and non-coding RNA expression. For instance, folate, choline, and actinin B12 are methyl donors; indimente intache intake leads to global hypomethylation, which may activate pro- ematory genes or silence - promoting genes. Studies in animail models shoat that a matinate hipereid -fat diet induces hypermethylation of the Foxpgene - contric.
