Perivascular microglial cells of the CNS are bone marrow-derived and present antigen in vivo

Hickey, William F., Kimura, Hiromitsu·1988·Science

Abstract

A crucial question in the study of immunological reactions in the central nervous system (CNS) concerns the identity of the parenchymal cells that function as the antigen-presenting cells in that organ. Rat bone marrow chimeras and encephalitogenic, major histocompatability-restricted T-helper lymphocytes were used to show that a subset of endogenous CNS cells, commonly termed "perivascular microglial cells," is bone marrow-derived. In addition, these perivascular cells are fully competent to present antigen to lymphocytes in an appropriately restricted manner. These findings are important for bone marrow transplantation and for neuroimmunological diseases such as multiple sclerosis.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The positive results of HSC transplantation into cALD patients indicated a role for brain microglia because microglia were thought to originate in bone marrow at that time.

    “The positive results of HSC transplantation into cALD patients [24,356] indicated a role for brain microglia because microglia were thought to originate in bone marrow at that time [357].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
