Hypothesis

Blocking TREM2 would repolarise tumour-associated macrophages and restore T-cell infiltration in PDAC allografts.

What failed

Macrophage phenotype shifted on flow cytometry but tumour growth curves showed no separation from isotype control.

Why

Monocyte recruitment upregulated in compensation, repopulating the niche with a functionally similar population — a redundancy the single-receptor block does not address.

Research ideas from this failure

Unvetted lead — read the papers

New hypotheses this failure suggests, each with a crucial experiment, a rival explanation of the original result, and the papers it rests on. Written by AI from paper titles and abstracts found on OpenAlex (and Europe PMC, for life and health sciences).

Not available for example entries: this one describes an invented experiment, and ideas built on it would be fiction.
