Thymosin β4 (Tβ4) and Tβ10 immunostaining in patients with primary Sjögren’s syndrome (pSS) and sicca symptoms and other autoimmune diseases. a Tβ10 in patients with pSS: immunoreactive granules in acinar cells. b Tβ4 in patients with pSS: No immunoreactivity is detected in acinar and ductal cells. c Tβ10 in patients with sicca syndrome and rheumatoid arthritis (ss/RA): Strong immunostaining is observed in ductal cells. d Tβ4 in patients with ss/RA: No reactivity is observed in either acinar or in ductal cells. e Tβ4 in patients with systemic sclerosis and sicca syndrome (ss/SSc): Granular immunostaining is observed in acinar cells. f Tβ10 in patients with ss/SSc: Immunoreactivity is observed mainly in serous acinar cells
