提前几天就通知今天要火警演练,这次比以前更离谱,要一直走到楼下并到街对面集合
,40多层楼房,于是乎大家都今天work from home了,一堆懒人,呵呵
现在办公室里空荡荡地,比圣诞节都清静

A vaccine targeting mutant IDH1 induces antitumour immunity
Monoallelic point mutations of isocitrate dehydrogenase type 1 (IDH1) are an
early and defining event in the development of a subgroup of gliomas1, 2, 3
and other types of tumour4, 5, 6. They almost uniformly occur in the
critical arginine residue (Arg 132) in the catalytic pocket, resulting
in a neomorphic enzymatic function, production of the oncometabolite 2-
hydroxyglutarate (2-HG)7, 8, genomic hypermethylation9, 10, 11, genetic
instability and malignant transformation12. More than 70% of diffuse grade
II and grade III gliomas carry the most frequent mutation, IDH1(R132H) (ref.
3). From an immunological perspective, IDH1(R132H) represents a potential
target for immunotherapy as it is a tumour-specific potential neoantigen
with high uniformity and penetrance expressed in all tumour cells13, 14.
Here we demonstrate that IDH1(R132H) contains an immunogenic epitope
suitable for mutation-specific vaccination. Peptides encompassing the
mutated region are presented on major histocompatibility complexes (MHC)
class II and induce mutation-specific CD4+ T-helper-1 (TH1) responses. CD4+
TH1 cells and antibodies spontaneously occurring in patients with IDH1(R132H
)-mutated gliomas specifically recognize IDH1(R132H). Peptide vaccination of
mice devoid of mouse MHC and transgenic for human MHC class I and II with
IDH1(R132H) p123-142 results in an effective MHC class II-restricted
mutation-specific antitumour immune response and control of pre-established
syngeneic IDH1(R132H)-expressing tumours in a CD4+ T-cell-dependent manner.
As IDH1(R132H) is present in all tumour cells of these slow-growing
gliomas15, a mutation-specific anti-IDH1(R132H) vaccine may represent a
viable novel therapeutic strategy for IDH1(R132H)-mutated tumours.
请这方面的牛人谈谈。挺牛的。前几天还讨论肿瘤免疫问题,现在针对IDH1突变的疫苗
都出来了。执行速度才是真的。

P53突变的疫苗已经做了好几个临床试验了,这个能发NATURE, 一个是现在免疫治疗热
,第二个可能是metabolism也热吧。从scientific角度来说,没有太新的东西,从应用
角度来说,这个是大家都在做的,各种常见的突变,都会做成治疗性疫苗,这也是我们
正在做的,没想到他们还能发到NATURE。

我不是做这个的,只是对immunotherapy感兴趣。参考文献:
Rituximab resistance
Rituximab has become a ubiquitous component of treatment regimens for
follicular non-Hodgkin lymphoma. Despite widespread clinical use, the
mechanisms by which tumor cells resist rituximab-mediated destruction remain
unclear. Rituximab relies in part on immune effector mechanisms for its
antitumor effect, and thus resistance may be mediated not only by intrinsic
tumor-cell alterations but also by the host immunological environment. In
this article, we explore the mechanisms of action of rituximab, the
incidence of rituximab resistance, and potential mechanisms of resistance.
Finally, we discuss novel approaches to modulate the antibody, the tumor
cell, and the host immunologic environment to overcome rituximab resistance.
Further research into the mechanisms of rituximab resistance will be
essential to improving the efficacy of anti-CD20 therapy in NHL, and may
also pay dividends in the optimization of monoclonal antibody therapy across
a wide range of diseases.
