BACKGROUND: Rasmussen encephalitis (RE) is a rare neuroinflammatory disease
characterized by intractable seizures and progressive atrophy on one side of the
cerebrum. Perivascular cuffing and clusters of T cells in the affected cortical
hemisphere are indicative of an active cellular immune response. METHODS:
Peripheral blood mononuclear cells (PBMCs) and brain-infiltrating lymphocytes
(BILs) were isolated from 20 RE surgery specimens by standard methods, and CD3(+)
T cell populations were analyzed by flow cytometry. Gamma delta T cell receptor
spectratyping was carried out by nested PCR of reversed transcribed RNA extracted
from RE brain tissue, followed by high resolution capillary electrophoresis. A
MiSeq DNA sequencing platform was used to sequence the third complementarity
determining region (CDR3) of ?1 chains. RESULTS: CD3(+) BILs from all of the RE
brain specimens comprised both ?? and ?? T cells. The median ??:?? ratio was 1.9
(range 0.58-5.2) compared with a median ratio of 7.7 (range 2.7-40.8) in
peripheral blood from the same patients. The ?? T cells isolated from brain
tissue were predominantly CD8(+), and the majority of ?? T cells were CD4(-)
CD8(-). Staining for the early activation marker CD69 showed that a fraction of
the ?? and ?? T cells in the BILs were activated (median 42%; range 13-91%, and
median 47%; range 14-99%, respectively). Spectratyping T cell receptor (TCR)
V?1-3 chains from 14 of the RE brain tissue specimens indicated that the ?? T
cell repertoire was relatively restricted. Sequencing ?1 chain PCR fragments
revealed that the same prevalent CDR3 sequences were found in all of the brain
specimens. These CDR3 sequences were also detected in brain tissue from 15 focal
cortical dysplasia (FCD) cases. CONCLUSION: Neuroinflammation in RE involves both
activated ?? and ?? T cells. The presence of ?? T cells with identical TCR ?1
chain CDR3 sequences in all of the brain specimens examined suggests that a
non-major histocompatibility complex (MHC)-restricted immune response to the same
antigen(s) is involved in the etiology of RE. The presence of the same ?1 clones
in CD brain implies the involvement of a common inflammatory pathway in both
diseases.
