免疫學・癌症免疫學・基因與分子生物學

林麗君博士的科研工作橫跨免疫學、遺傳學、癌症免疫學、細胞與分子生物學及病毒學。早期研究涉及病毒與宿主細胞之間的分子機制及免疫球蛋白基因重組,其後主要集中於B細胞、NK細胞及樹突狀細胞的發育、存活與功能調節,以及Leptin、BAFF、TNF家族細胞因子等免疫訊號在炎症、自體免疫及免疫細胞恆定中的作用。

近年的研究進一步延伸至癌症免疫學與個人化新抗原(Neoantigen)研究,探索如何從晚期癌症患者的循環腫瘤細胞識別個人化腫瘤新抗原。

藤田成晴院長 Dr. Shigeharu Fujita

樹突狀細胞・T細胞・免疫調節

藤田成晴院長的科研工作主要集中於樹突狀細胞、T細胞及免疫調節機制,深入研究調節性樹突狀細胞如何影響T細胞反應,以及如何參與全身性炎症、過敏性呼吸道炎症及慢性移植物抗宿主病等免疫反應。

其研究亦涉及免疫細胞轉錄體與蛋白質體分析,以及早期的糖生物學與細胞分子研究。其後科研方向進一步延伸至WT1特異性細胞傷害性T細胞及癌症免疫學,並於近年參與個人化新抗原研究。

科研成果曾發表於 Blood、Journal of Allergy and Clinical Immunology、Allergology International、Bioinformatics、Glycobiology、Frontiers in Immunology 等國際學術期刊。

從樹突狀細胞與T細胞研究走向癌症免疫治療

藤田院長其後的科研由免疫調節進一步延伸至癌症免疫學。

2009年至2017年間,他於東京大學醫科學研究所附屬醫院參與人類WT1特異性細胞傷害性T細胞(WT1-specific Cytotoxic T Lymphocytes)誘導研究

WT1是多種癌症中受到廣泛研究的腫瘤相關抗原。這段科研經歷將藤田院長早期的樹突狀細胞與T細胞研究,進一步連結至癌症免疫學及其後的癌症免疫細胞治療。


2025|個人化新抗原癌症免疫研究

兩個研究方向,在個人化癌症免疫治療上交匯

2025年,林麗君博士與藤田成晴院長共同參與的個人化新抗原研究發表於國際免疫學期刊 Frontiers in Immunology

A Method for Identifying Neoantigens through Isolation of Circulating Tumor Cells Using Apheresis among Patients with Advanced-Stage Cancer

Frontiers in Immunology. 2025.

研究探索從晚期癌症患者中分離循環腫瘤細胞(Circulating Tumor Cells, CTCs),取得患者自身癌症的分子資訊,並進一步分析及識別患者特有的新抗原(Neoantigens)

研究方向將:

患者自身癌症資訊

循環腫瘤細胞分離

腫瘤分子與基因變異分析

個人化新抗原識別與預測

連結成更個人化的癌症免疫研究方向。

從群體化的治療思維,走向以每位患者腫瘤特徵為基礎的個人化設計。

這項研究亦代表林麗君博士與藤田成晴院長多年來在免疫學、樹突狀細胞及癌症免疫領域的研究,進一步交匯於個人化癌症免疫治療的共同方向。

科研如何連結臨床

基礎研究與臨床治療並不是同一件事。

一項機制在實驗室中成立,並不代表已經證實能改善患者的臨床結果;同樣,一項早期人體研究亦需要更大型及更長期的研究進一步驗證。

因此,我們重視的不只是「有沒有研究」,而是:

研究屬於哪一個證據層級?
研究的是甚麼機制?
是否已進入人體研究?
研究結果能否適用於眼前這一位患者?

Caring from Japan 希望把科研與臨床之間的距離說得更清楚,讓患者在了解新醫療技術的同時,也了解現階段科學證據的範圍與限制。
