Project description:While skin and oral mucosa share many morphological similarities, oral mucosal wounds heal more rapidly than skin wounds. Epithelial cells from oral mucosa exhibit increased migratory and proliferative capacities when compared to cells from skin, suggesting that the improved repair of mucosa may involve intrinsic differences in epithelial cells. This is an exploratory experiment to define the differential microRNA expression of baseline unwounded skin and oral mucosa epithelium.

Project description:Wound healing within the oral mucosa results in minimal scar formation compared to wounds within the skin. We have recently demonstrated distinct differences in the ageing profiles of cells (oral mucosal and patient-matched skin fibroblasts) isolated from these tissues. We hypothesize that the increased replicative potential of oral mucosal fibroblasts may confer upon them preferential wound healing capacities. Passage-matched early cultures of oral mucosal fibroblasts and skin fibroblasts demonstrated distinct gene expression profiles with a number of genes linked to wound healing/tissue repair. We analyzed the gene expression profiles of oral mucosal and patient-matched skin fibroblasts for multiple patients both prior to (0h) and (6h) following a wounding stimulus. Differences in the gene expression profiles of oral mucosal and patient-matched skin fibroblasts were anlazyed for multiple patients both prior to (0h) and (6h) following a wounding stimulus. Serum starvation and subsequent stimulation provides a model for wounding and RNA extracted at 0h and 6h following this stimulus was hybridized to Affymetrix microarrays for analysis. We sought to compare the expression profiles both between oral and normal fibroblasts, in both serum depleted and stimulated conditions and also compare differences between patients.

Project description:The oral mucosal pellicle is a thin lubricating layer generated by the binding of saliva proteins on epithelial oral cells. The protein composition of this biological structure has been to date studied by targeted analyses of specific salivary proteins. In order to perform a more exhaustive proteome characterization of pellicles, we used TR146 cells expressing or not the transmembrane mucin MUC1 and generated pellicles by incubation with human saliva and washing to remove unbound proteins. A suitable method was established for the in vitro isolation of the mucosal pellicle by “shaving” it from the cells using trypsin. Comparison of pellicle and saliva compositions evidenced the adsorption of proteins not previously reported as pellicle constituents such as proteins of the PLUNC family. Pellicles formed on TR146 and TR146/MUC1 were also analyzed and compared by protein label-free quantification.

Project description:Immune responsiveness at barrier surfaces is tailored to the exposures of each tissue. In the oral mucosa, mechanisms by which a permeable epithelium coexists with diverse microbiota and maintains integrity during inflammatory pathology remain poorly understood. We compile a multi-omics spatial map of this exposed mucosal microenvironment and uncover remarkable immune zonation with organization that is preserved even during inflammatory disease. At steady state, we identify a dynamic epithelium at the tooth interface marked by a tonic inflammatory signature which is underlined by a layer of neutrophils and a zone of APC-lymphocyte aggregates. During disease, inflammatory zones expand and organize into immature tertiary lymphoid structures, suggesting local antibody production. This spatial immune organization meets the demands for continuous protection in health and expands in function and complexity during disease while preserving key elements of zonation. Our work provides insights into tissue-specific wiring of immunity at a vulnerable human mucosal barrier.

Project description:The establishment of mucosal homeostasis after birth involves mutual development of the microbiota and the immune system, with each mucosal barrier has specific mechanisms. Here, we show that in utero-delivered maternal IgG antibodies are translocated to the salivary glands and secreted to the neonatal saliva. As a result, the microbial burden of the neonate oral cavity and salivary glands is reduced. In the absence of maternal antibodies, oral dendritic cells migrate in higher frequencies to the salivary glands resulting in elevated activation of T and B cells, while dampening T regulatory cells. The IgG/IgA balance in the adult saliva was also dysregulated. The absence of maternal antibodies further regulates the adult gingival immunity, a key oral barrier, increasing alveolar bone loss during experimental periodontitis. This work reveals the importance of the salivary-oral axis during neonatal life via maternal antibodies, orchestrating local mucosal immunity and protecting against pathological damage in adulthood.

Project description:The morphology and the behavior of skin and oral tissue keratinocytes are different. One significant dissimilarity between the two sites is the response to injury. Oral and skin keratinocytes have intrinsic differences in the response to injury and such differences are reflected in gene expression profiles. We used microarrays to investigate differences in global gene expression patterns between baseline skin and oral epithelium sheets without their underlying connective tissue. Paired skin and oral epithelium was separated from the dermis for RNA extraction and hybridization on Affymetrix microarrays. Skin epidermal tissues were obtained from the tail of mice and oral epidermal tissues were obtained from the hard palate. Enzymatically isolated epithelium was used for analysis.
