Upregulation of proinflammatory pathways detected in tear fluid of pSS patients. For functional analysis of the proteomics data, DAVID (v 6.7, https://david.ncifcrf.gov) was applied using a FDR with a maximum 5% cut-off, and cellular processes for the upregulated proteins in the pSS patients were identified. FunRich (http://www.funrich.org/) was then used to visualise the fraction of proteins involved in each of these upregulated signalling pathways. a Upregulated signalling pathways identified in the pSS patients, as compared to non-SS sicca controls. b Comparing pSS patients to healthy controls helped detect similar cellular processes as with the non-SS subjects, affecting both innate and adaptive immunological processes. Percentage values indicate the amount of overexpressed proteins involved in upregulating each of the cellular processes identified
