to your head, where the pain is,
効果をもたらすために
and various other organs first.
その他様々な内臓器官を通ります
and painless way of delivering
体内に取り込む為の
any medication leads to its dilution.
しまうという欠点があります
particularly in HIV patients.
とっては大きな問題です
the virus in the blood,
ウイルス濃度を低め
for their adverse side effects,
by the time they get to the blood,
到達するまでの間に
they get to the sites
体内で最も肝心な部位
within the HIV viral reservoirs.
到達する前に希釈されてしまうのです
such as the lymph nodes,
as well as the lungs --
get delivered in the blood
摂取していても
consistent anti-HIV drugs therapy.
成分がうまく運ばれないのです
and infect new cells in the blood.
細胞に感染してしまいます
HIV with the current drug treatment,
治療法においてとても大きな問題です
that must be swallowed by patients.
ならないのです
within its reservoir sites,
効果が弱まるというリスク無しで
方法はないのだろうか?」
the answer was just before my eyes:
答えはすぐ目の前にありました
手術に使えるのならば
届ける事も可能かもしれない
we are currently using laser pulses
というものを使い
開ける実験が行われています
immediately in HIV-infected cells,
開閉する穴をつくることで
送り込む仕組みです
but super-tiny laser beam
非常に強力で尚且つ微小なレーザーを
細胞膜に照射します
in liquid containing the drug.
浸っているところを照射されるので
while the cell swallows the drug
成分が中まで浸透するのです
becomes immediately repaired.
this technology in test tubes
this technology in the human body,
人体のために利用する事
through a three-headed device.
in the site of infection.
蛇行し たどり着きます
which is a drug-spreading sprinkler,
スプリンクラーを利用し
at the site of infection,
to poke those cells open.
細胞に微小な穴をあけるのです
like much right now.
段階にありますが
this technology can lead
この技術はいつか
of HIV in the body.
可能にしてくれる事でしょう
導き出してくれる治療法なのです
ABOUT THE SPEAKER
Patience Mthunzi - Laser scientistPatience Mthunzi wants to use lasers to deliver medicines more effectively.
Why you should listen
Patience Mthunzi is a research group leader at the Council for Scientific and Industrial Research in Pretoria, South Africa. There, she uses laser "tweezers" to try and separate diseased cells from healthy ones. She's also developed a way to use laser pulses to target drug delivery into cells.
Born in Soweto, Patience got her PhD in physics from the University of St. Andrews in Scotland. In 2012, she was named one of 20 Youngest Power Women in Africa by Forbes magazine; that same year she was given the Order of Mapungubwe for her contribution in the field of biophotonics. She's also a TED Fellow.
