OBJECTIVE
To localise and characterise follicular
dendritic cells (FDC) present in autoimmune lesions of primary Sjogren syndrome.
METHODS
Cryostat sections of labial salivary
glands from 15 patients with primary Sjogren syndrome were examined by
an indirect immunoperoxidase technique and monoclonal antibodies to a
panel of dendritic cell markers. Tonsils from two controls were also
examined for the same markers.
RESULTS
FDC were localised in the centre of 75%
of lymphoid focal structures in labial salivary gland biopsies. FDC in
labial salivary glands of patients with primary Sjogren syndrome
expressed CD35, CD11c, and CD106 (VCAM-1) in a pattern similar to FDC
in tonsils, but they did not express either CD14 or CD11b. This
indicates that they may not be of myeloid origin, while FDC in
tonsillar lymphoid follicles strongly expressed both CD14 and CD11b.
FDC in labial salivary glands of patients also lacked VLA-2
and
VLA-3
, which were expressed by FDC in tonsils.
CONCLUSIONS
The characteristic phenotype and
origin of these cells may be of importance in the immune responses
involved in Sjogren syndrome and the retention of infiltrating
lymphocytes in the glands.
