Since the mitochondria have their own DNA, it follows that they can re -

produce independently of the host cell. Thus, the number of mitochondria

can vary in time within a given cell or cell type. Various treatments such as

some antifungal tr eatments can actually kill many mito chondria. After the

treatment is stopped, the mitochondria will start multiplying a gain and their

population will eventually recover to normal le vels. Recently, it ha s been dis-

covered that mitochondria also play an essential role in mechanisms other

than energy generation. For ins tance, mitochondria can be the target of the

immune system response [301]. Thus, it has rec ently been shown that
