MOTO-CAR技術取得專利,未來或發展為通用型癌症治療產品
美國楊百翰大學研究團隊透過奈米基因工程改造巨噬細胞,在小鼠實驗中使實體腫瘤縮小46%,體外測試中24小時內清除90%肺癌細胞。技術已取得專利並授權生技公司,但仍處於臨床前研發階段,尚未進行人體臨床試驗,相關成果亦未在同行審查期刊發表。

現行免疫療法對難治的實體腫瘤效果有限,科學家將目光轉向巨噬細胞。CAR-T療法主要用於血癌,以改造T細胞為主,而MOTO-CAR技術鎖定能輕易穿透實體腫瘤內部的巨噬細胞,試圖突破傳統免疫細胞難以攻入腫瘤微環境的瓶頸。

〔編譯陳成良/綜合報導〕現行免疫療法,有時針對難纏的實體腫瘤時,效果差強人意;如今科學家將目光轉向人體的另一支免疫主力。美國楊百翰大學(BYU)研究團隊透過奈米基因工程,改造專門吞噬異物的「巨噬細胞」,在初步動物實驗中,成功使小鼠體內的實體腫瘤縮小達46%。
科學新聞網站《MedicalXpress》報導,這項名為「MOTO-CAR」的新技術已取得專利。與目前常用於治療血癌、以改造「T細胞」為主的CAR-T療法不同,該技術鎖定能輕易穿透實體腫瘤內部的巨噬細胞,試圖突破傳統免疫細胞難以攻入腫瘤微環境的瓶頸。
借力巨噬細胞穿透力 重啟免疫攻擊
在實驗設計中,研究團隊利用奈米粒子將基因指令精準送入巨噬細胞,重新「武裝」這群免疫衛士。改造後的巨噬細胞不僅能在體內辨識並吞噬癌細胞,還能將腫瘤的抗原特徵傳遞給其他免疫軍隊,喚醒整體防線形成長期免疫記憶。在早期的體外細胞培養測試中,該技術甚至在24小時內清除了90%的侵襲性肺癌細胞。
研究團隊表示,這項技術未來有望朝向預先製備的通用型產品發展,免去現行細胞療法極度耗時、昂貴的個別化製造難題。
不過,這項技術目前仍處於極早期的臨床前研發階段,不僅尚未展開人體臨床試驗,相關成果也尚未在同行審查的學術期刊發表正式論文。該專利目前已授權予研究主持人歐尼爾(Kim O’Neill)創辦的生技公司推進後續測試,其在人體內的安全性與實際療效,仍有待漫長驗證。

A Hong Kong paediatric expert urges parents to vaccinate children against influenza ahead of cooler weather, warning of overlapping summer and winter flu waves after 29 severe paediatric cases and two deaths this season.

The Affiliated Hospital of National Yang-Ming Chiao Tung University celebrated its 130th anniversary and held the 16th International Medical Symposium in conjunction with National University of Yilan on the 7th, focusing on topics such as sustainable medical care, prevention and treatment of childhood myopia, cardiovascular care, and generative AI. Dean Huang Zhixian and President Lin Qihong delivered speeches respectively, and demonstrated the local results of Yilan's reduction of myopia rate among young children from 15.4% to about 8%.

The Taichung Veterans Affairs Center broke ground on the construction of a medical science and technology building at a cost of 4.082 billion yuan. Executive Director Zhuo Rongtai attended and said that our country's health insurance has been recognized internationally, and the government's medical and health insurance budget has increased year by year, exceeding one trillion yuan. The building is expected to be completed in November 2029 and opened in April 2030. It will have core facilities such as an international conference center and an artificial intelligence research center.

There is one new imported case of dengue fever in Tainan. The case is a Chinese female in her 40s from Yongkang District. She developed symptoms 4 days after returning from a trip to Vietnam as an employee and was diagnosed at Annan Hospital. She is the 17th imported case in Tainan this year. The disease management unit has launched emergency spray prevention and control, environmental breeding source removal and vector mosquito density surveys for his residence. As of November 6, there have been a total of 238 cases in the country, including 221 imported cases. Vietnam has the largest number of infected countries.

Salary data of Changhua Christian Medical Center has been exposed. The average monthly salary of thoracic surgeons is 1.577 million yuan, setting a new ceiling in the industry; cardiac surgery is 1.439 million yuan, anesthesiology is 609,000 yuan, and dermatology is 324,000 yuan. Chief Dean Chen Mukuan pointed out that openness and transparency in procurement negotiations and saving operating costs to reward employees are the keys to supporting high salaries and low out-of-pocket medical expenses.

The FDA is investigating a risk of neoplasia, including malignancy, associated with Novartis' gene therapy Zolgensma. The Swiss drugmaker disclosed two cases of tumors in children linked to the therapy and reported nine tumor cases overall among patients treated since its 2019 approval.
