<unk> , or<unk> , is an increase in the<unk>  of the<unk>  membranes to molecules of less than 1500 Daltons in molecular weight. <unk>  results from opening of<unk>  pores, also known as the<unk>  pores or<unk> P.  The<unk>  pore is a protein pore that is formed in the membranes of<unk> under certain pathological conditions such as traumatic brain injury and stroke.  Induction of the<unk><unk>  pore can lead to<unk>  swelling and cell death and plays an important role in some types of apoptosis.
The<unk> P was proposed by Haworth and Hunter in 1979 and has since been found to be involved in, among other things, neurodegeneration, a process that results in damage and death of neurons.<unk>  is frequently studied in liver cells, which have especially large numbers of<unk>
