Could this be a possible treatment for HIV/AIDS: Synthesize a peptide nucleic acid antisense oligonucleotide for HIV�s gag gene�s mRNA. The reason for using PNA is that it is substantially more resistant to enzyme degradation by nucleases and proteases. The reason for choosing the gag gene is that it�s proteins, p24, p17, p7, and p6, code for the basic physical infrastructure of HIV; w/o these key proteins, there is no HIV. Then, encapsulate the oligonucleotides in liposomes studded w/ anti-CD4 antibodies. This will ensure 1) toxicity is limited�cf Ambisome, the liposomal preperation of amphotericin B�2) the biologic goes only where it�s needed, which is the cytoplasm of CD4+ T-cells. Decorating the liposome w/ anti-CD4 antibodies will trigger endocytosis, in my limited knowledge, at least. I predict low toxicity and high efficacy in reducing the patient�s viral load to hopefully 0 copies/ml. Maybe, when I'm doing my PhD or MD dissertation --a long ways off, see below--, I could do it on this, patent the resulting product --ie the PNA oligonucleotide itself--, and license it to Genentech or Hybridon for further development into a marketable biologic. What are your thoughts? Should LNA instead of PNA be used? Cell- penetrating peptides vs. liposomes? Targeting the gag gene vs. targeting the pol gene? Using anti-CD4 mAbs vs. anti-gp160 mTcRs as a drug targeting device? Are there any publications about this subject? Another drug could be a mTcR for gp160, linked to FasL...this should cause formation of DISC, leading to the cell's eventual apoptosis. And since it's linked to an mTcR that only recognizes gp160, only HIV- infected cells will undergo apoptosis. And since apoptosis is an organized "format c:" of the cell, the virons will also be destroyed!!! In your expert opinions, do you believe these will cause remission of HIV/AIDS? Partial or complete? And, just for fun, what do you think the generic names would be for these biologics? Brand names? BTW, if this helps you answer, I'm a 16.5 year old community college freshman who hopes to have a career as a physician-scientist. Thanks!!!!
