How the Complement-ARIE Challenge winners fit dismech

Written 2026-10-14 against dismech main at commit 8fe34ebd4, for issue #14176. Source: the NIH Common Fund Complement-ARIE Challenge Prize winner summaries (page last reviewed 2025-11-21), which describe 20 winning proposals for non-animal models.

This report sits beside the assay and NAM inventory and its companions. The inventory covers what has already been tried inside dismech. This report covers one outside source of candidate models and asks, for each, whether it has a dismech home.

Summary

  • Four winners have a published model that could be curated into an existing entry now: the miniJoint and the click-chemistry cartilage assay into Osteoarthritis, the orofacial epithelial-mesenchymal microplate into Cleft Lip/Palate, and the feto-maternal interface organ-on-chip into Chorioamnionitis or Preterm Premature Rupture of the Membranes. All four entries have no experimental_models today.
  • Three more have a published model that needs a decision first. For the ABMACT agent-based model and the CAR T trial-on-chip, the full text has to settle which cancer entry they belong to (the published chip is leukaemia, not the pancreatic cancer the proposal describes). The OASIS Cell Painting hepatocyte screen is a preprint and is only partly disease-specific, which makes it fringe in the same way as the ToxCast endpoints.
  • Three have no published model yet that matches the proposal: the Alzheimer blood-brain-barrier chip, the atherosclerosis tissue array, and the rheumatoid arthritis synovial organoids.
  • Ten do not fit a disease entry. Three are not models (E-validation, ATHENA-N and the NAMKG registry). Five are platforms published without a disease (4D bioprinting, organoid intelligence, the skin equivalent, the multi-compartment lymph node chip, the engineered heart constructs). Two are disease-agnostic toxicology (DeTox and the canine testis organoid).

The proposals themselves are not citable evidence. Everything below that says a model "fits" refers to the published paper named in that row, not to the challenge summary.

How the table was built

  • Published model. PubMed was searched on 2026-10-14 by team-member names combined with the model's subject. Every PMID below was retrieved from PubMed and its abstract read. "None found" means these searches returned no paper describing the proposed model; it does not prove that none exists.
  • Target entry. The kb/disorders/ or kb/modules/ file the model would attach to, with its count of experimental_models (or computational_models) at the commit above.
  • Type. experimental_model_type (ExperimentalModelTypeEnum) or, for computational models, model_type (ComputationalModelTypeEnum). namo_type is a class in the current NAMO schema (56 classes), or "none" where no class fits.
  • Tie. The row of the "what ties the model to the disease" table in #13602: the cells carry the lesion; unaffected cells given the exposure that causes the disease; unaffected cells given a risk-factor exposure; unaffected cells given the treatment; a wild-type target with a chemical and no disease context. "No disease" marks a model published without any disease, which that table does not cover.

Notes on individual rows

Osteoarthritis gets two different kinds of model. The miniJoint (row 15) builds joint tissues from healthy mesenchymal stem cells and adds IL-1β, so the disease is imposed rather than present; a link from it needs a CAUSE_UNREPRESENTED divergence. The cartilage explants in row 5 come from knee replacements, so the tissue carries the disease, but dismech has no experimental_model_type or NAMO class for an ex vivo explant and it would be recorded as OTHER with no namo_type.

The orofacial microplate repeats the Akura Twin problem. Row 9 is a micromachined plate with no perfusion, the same situation as the liver fibrosis plate in the NAMO vocabulary gaps note: MicrophysiologicalSystem is abstract and assumes microfluidics, so namo:CoCulture is the closest binding. The abstract does not say whether the cells are human, which the curator will need from the full text.

The pregnancy chip has two candidate entries. LPS on the decidua side models ascending infection, which is the cause of chorioamnionitis and a cause of membrane rupture. There is no Preterm Birth entry. Whichever entry is chosen, the chip's readouts are inflammatory cytokines by layer, so the target nodes should be inflammation nodes rather than the rupture itself.

Two published models are not the proposed model. In row 4 the team published a leukaemia chip, not the pancreatic cancer organoid chip they proposed. In row 10 the team published a canine testis organoid, not a human one. A canine organoid would need organism set to dog, the same species question the murine tissue slices raised in #9997.

OASIS belongs with the ToxCast question. Row 8 screens 1,085 compounds of mixed toxicity on normal hepatocytes. Only the hepatotoxic compounds give it a disease tie, so it falls between the "exposure that causes the disease" row and the "chemical, no disease context" row of #13602, where the ToxCast endpoints in

12858 also sit. The full study is a preprint.

Where this agrees with the inventory, and what it adds

The inventory's list of recurring blockers predicts most of the problems above:

Blocker in the inventory Winners that hit it
No NAMO class for non-perfused plates or ex vivo slices 5 (cartilage explants), 9 (microplate), 18 (lymph node slices)
No structured exposure, dose or donor population on a model 8 (1,085 compounds), 15 (IL-1β), 19 (LPS and four chemicals); the proposals for 2 (isogenic patient lines) and 18 (donors varying by sex, age, race and obesity) depend on donor information
No disease-agnostic assay record 6, 8, 10

Two things here are not in the inventory:

  • Multi-tissue systems. Rows 15, 18 and 19, and the proposal in row 2, couple several tissues in one device. experimental_models gives one tissue_term per model and namo_type is single-valued, so a chip with decidua, chorion and amnion, or a joint with bone, cartilage, synovium and fat, records one tissue.
  • Models with no disease. Five winners published a platform with no disease in it (rows 1, 14, 16, 18 and 20). Under #13602's framing these are not fringe disease models; they are not disease models at all, which supports the suggestion in that thread of a verdict for "belongs somewhere other than a disease entry".

Follow-up curation

Each "Fits" row is one curation issue, attaching the named paper's model to the named entry with modeled_mechanisms links and quoted evidence:

  1. Osteoarthritis: the miniJoint (PMID:35436042, PMID:36830751) and the cartilage explants (PMID:42011976).
  2. Cleft_Lip_Palate: the orofacial microplate (PMID:33634122).
  3. Chorioamnionitis or Preterm_Premature_Rupture_of_the_Membranes: the feto-maternal interface chip (PMID:33112317).
  4. After a full-text check of the cancer type: ABMACT (PMID:41673469) and the leukaemia trial-on-chip (PMID:40595437).

The "No paper yet" rows are worth re-checking when those teams publish.
