生物学界的高水平造假,看大家如何编故事,讲故事好听的吗?

一个广为接受的事实:LAG3 (a checkpoint molecule), 不管是否在别的细胞上表达

The same group and the same first author, they claimed in their 2016 Science
paper, that ‘LAG3 was primarily expressed in neurons because LAG3 was not
detectable in astrocytes or microglia’. (Science. 2016 Sep 30; 353(6307):
aah3374),

So many good labs had CLEARLY shown and approved that LAG3 is thought to be
largely in microglia. If the LAG3 antibodies they used were specific, LAG3
expression in microglia should be detected in their 2016 Science paper, why
they say "LAG3 was expressed in neurons but not in microglia?

Now, Mao et al NEW preprint, they show the expression of LAG3 in microglia.
(Aplp1 and the Aplp1-Lag3 Complex facilitates transmission of pathologic α-
synuclein, https://www.biorxiv.org/content/10.1101/2021.05.01.442157v1 )

And interestingly, in this preprint (Aplp1 and the Aplp1-Lag3 Complex
facilitates transmission of pathologic α-synuclein, https://www.biorxiv.org
/content/10.1101/2021.05.01.442157v1 ), using LAG3-YFP transgenic mice to
verify LAG3 protein expression in (mouse) neuron look good, but why the GFP
antibody was used to stain YFP? Artifacts? The anti-GFP staining pattern was
not convincing, if you look their nuclei counterstaining, it seems very
like auto-fluorescence. Can this truly approve the neuronal expression of
LAG3, why not do solid and convincing studies like another preprint "LAG3 is
not expressed in human and murine neurons and does not modulate α-
synucleinopathies" (https://www.biorxiv.org/content/10.1101/2021.04.25.
441302v1 )

"The immunoreactivity of anti-GFP, which recognizes YFP co-localized with
MAP2 immunostaining in the spinal cord, olfactory bulb, striatum, substantia
nigra pars compacta, hippocampus, cortex, cerebellum and brainstem (fig.
S3A). The lack of immunoreactivity of anti-GFP in WT mice indicates that the
anti-GFP immunoreactivity is specific in Lag3L/L-YFP mice (fig. S3B). In
addition, anti-GFP colocalizes with IBA1 immunostaining, but not GFAP
immunostaining (fig. S3B)"

为了名和利吧: fame and money,学术界不就是教授的title,grant。

虽然这个发现赶不上韩春雨的NgAgo, 但是也是大发现啊,对于一个以 synuclein 为病
理特征的帕金森氏疾病是一个巨大突破,想想只要阻断这个LAG3,不就搞定了吗?

这个算是编造故事吧
