It has been recently reported that telocytes, a stromal (interstitial) cell
subset involved in the control of local tissue homeostasis, are hampered in the
target organs of inflammatory/autoimmune disorders. Since no data concerning
telocytes in minor salivary glands (MSGs) are currently available, aim of the
study was to evaluate telocyte distribution in MSGs with normal architecture,
non-specific chronic sialadenitis (NSCS) and primary Sjögren's syndrome
(pSS)-focal lymphocytic sialadenitis. Twelve patients with pSS and 16 sicca
non-pSS subjects were enrolled in the study. MSGs were evaluated by haematoxylin
and eosin staining and immunofluorescence for CD3/CD20 and CD21 to assess focus
score, Tarpley biopsy score, T/B cell segregation and germinal center (GC)-like
structures. Telocytes were identified by immunoperoxidase-based
immunohistochemistry for CD34 and CD34/platelet-derived growth factor receptor ?
double immunofluorescence. Telocytes were numerous in the stromal compartment of
normal MSGs, where their long cytoplasmic processes surrounded vessels and
encircled both the excretory ducts and the secretory units. In NSCS, despite the
presence of a certain degree of inflammation, telocytes were normally
represented. Conversely, telocytes were markedly reduced in MSGs from pSS
patients compared to normal and NSCS MSGs. Such a decrease was associated with
both worsening of glandular inflammation and progression of ectopic lymphoid
neogenesis, periductal telocytes being reduced in the presence of smaller
inflammatory foci and completely absent in the presence of GC-like structures.
Our findings suggest that a loss of MSG telocytes might have important
pathophysiological implications in pSS. The specific pro-inflammatory cytokine
milieu of pSS MSGs might be one of the causes of telocyte loss.
