Jia Lisa Parasited -

| Host Gene | Normal Function | Parasite‑Induced Change | Functional Consequence | |-----------|----------------|--------------------------|------------------------| | | Cytokine signaling; promotes Th17 differentiation. | Up‑regulated 4.2‑fold (peak at 12 h). | Skews immune response toward a regulatory phenotype, reducing early inflammation. | | FOXP3 | Treg development. | Up‑regulated 2.8‑fold (peak at 18 h). | Enhances Treg population, facilitating immune tolerance to the parasite. | | IL‑12β | Th1 polarizing cytokine. | Down‑regulated 3.5‑fold (peak at 24 h). | Dampens IFN‑γ production, weakening anti‑parasite immunity. | | MUC2 | Goblet‑cell mucin; protects intestinal epithelium. | Down‑regulated 5.1‑fold (peak at 36 h). | Weakens mucus barrier, potentially aiding parasite invasion of deeper crypt cells. |

P. symbiotica delivers exomessenger RNAs (≈ 200 nt) that act as microRNA mimics , binding to host 3′‑UTRs and repressing translation of immune‑activating genes while promoting regulatory pathways. jia lisa parasited

The next time you watch Parasite , watch Jia Lisa’s face as she eats the fancy food in the Park’s kitchen. Watch her hands shake when she sneaks down the stairs. She is not a parasite. She is a warning. | Host Gene | Normal Function | Parasite‑Induced
