大部份的人體細胞均會藏有油脂。當細胞需要能源的時候，油脂可以在粒線體裡頭分解成為能源。876Please respect copyright.ＰＥＮＡＮＡG9Q3cuGCVk

（圖2）有科學家發現(Ref1)，當有細菌入侵細胞的時候，細胞的油脂數量會增加，但相應的體積亦會有所縮小。876Please respect copyright.ＰＥＮＡＮＡwZHYFJm54L

（圖3）油脂除了能量儲存功用外，亦提供了各種蛋白質聚集的地方。876Please respect copyright.ＰＥＮＡＮＡiagISwYfyk
譬如說，PLN5就是一種引領油脂抵達粒線體的蛋白質。876Please respect copyright.ＰＥＮＡＮＡbjf1cGMDPB

科學家在文中指出，當有細菌入侵細胞的時候，油脂上的PLN5蛋白質就會減少，取而代之會有各種與免疫系統有關的蛋白質黏附在油脂上，並傾向與細菌接觸。876Please respect copyright.ＰＥＮＡＮＡBZLYZQhXjW

箇中油脂上其中一種名為Cathelicidin的蛋白質便有著破壞部份細菌的外壁功效。876Please respect copyright.ＰＥＮＡＮＡ4LLLKVjvf7

（圖4）隨著油脂用作對付細菌的關係，油脂再也無瑕抵達粒線體作分解能源之用。因此在對抗入侵者期間，細胞亦會因而傾向轉用葡萄糖作為能量來源。876Please respect copyright.ＰＥＮＡＮＡqdPFWnxQ89

之於如何善用這種知識來研發對抗感染的療法，那將會是科學家們日後的命題。876Please respect copyright.ＰＥＮＡＮＡBrtuU6rdtU
