Figure Lengend Snippet: Investigation of protein signatures of diseases based on cVAE modeling. ( A ) Heatmap showing the top 10 protein markers for disease groups, including AD_PD_MG (AD_PD_MG vs. HC_ON_NMOSD), sub_AD (AD vs. PD_MG_HC), and sub_PD (PD vs. AD). ( B ) Relative abundance of the top protein marker in each group. ( C ) Overexpression of HSPG2 confirmed in PD patients compared to AD by ELISA (left, AD, n = 15; PD, n = 6); Overexpression of LRG1 confirmed in AD patients compared to HC and MG by ELISA (right, AD, n = 14; HC, n = 12; MG, n = 15). ( D ) Overexpression of LRG1 was characterized in AD patients compared to HC, PD, MG, ON, and NMOSD by LC-MS analysis ( n = 3, pooled samples)

Article Snippet: The protein concentrations in each sample (100 μL) were measured following the manufacturer’s instructions: HSPG2 (CUSABIO, China, CSB-EL010868HU) and LRG1 (Abcam, ab260066-1 × 96 t).

Figure Lengend Snippet: CMA maintains a functional MSCs-like secretome in PCs. ( A ) Representative pictures show periodontal ligament stem cells (PDLSCs) that can spontaneously differentiate into an osteogenic lineage (T0). ALP, Alcian Blue, and Oil Red positive PDLSCs are shown after being incubated for 14 days (T14) with the control vehicle (veh), with supernatants from WT PCs (WT sup) or with supernatants from KO PCs (KO sup). Scale bar: 100 µm. ( B-D ) Graph represents the quantification of levels of positive cells for ALP activity (osteogenic lineage), alcian blue (chondrocytes), and Oil Red O (adipocytes) staining, respectively. All data represent mean ± SD obtained from at least five experiments represented as dots, independently; *** p < 0.001; **** p < 0.0001 (ANOVA with Tukey’s post-test). ( E ) Quantification of the mRNA expression by qPCR of some genes involved in osteogenesis differentiation. Data show specifically the gene expression levels in PDLSCs (expressed as folds over control vehicle and normalized to Actb as the housekeeping reference gene expression) incubated with WT PCs sup or KO PCs sup. All data represent mean ± SD obtained from at least four experiments represented as dots, independently; ** p < 0.001; *** p < 0.0001 (ANOVA with Tukey’s post-test). ( F ) Venn diagram of the secretome analysis of identified proteins in WT PCs and KO PCs. WT PCs secrete 10 exclusive proteins, sharing 15 proteins in common with KO PCs, which have 3 specific secreted proteins. ( G ) Chart shows the analysis of functional groups associated with pro-regenerative (left) and pro-inflammatory (right) mechanisms. These groups represent the percentage of proteins identified in both the secretome of WT PCs (right) and KO PCs (right) cultures from the total amount of identified proteins by mass spectrometry. The ratio between KO and WT PCs represents the most secreted proteins by each cell type. Twelve (34 %) of the proteins secreted by WT PCs were related to tissue development and cell differentiation functions (such as UHRF1 (ICBP90)-binding protein 1, follistatin-related protein 1, and SPARC), nine (26 %) were related to wound healing (such as plasminogen activator inhibitor 1 and perlecan), nine (26 %) to extracellular matrix organization (such as beta-actin-like protein 2) and five (17 %) to angiogenesis functions (such as antithrombin III). On the other hand, four (45 %) of the proteins secreted by KO PCs were related to extracellular matrix assembly (such as dipeptidyl aminopeptidase-like protein 6 and collagen alpha-1 chain), three (33 %) were related to inflammatory response (such as complement C3), and two (22 %) were related to lipid metabolism (such as long-chain-fatty-acid-CoA ligase 3).

Figure Lengend Snippet: Stemness and anti-inflammatory properties of the CMA-dependent secretome of PCs. ( A ) Representative images of PDLSCs differentiation after incubation with proteins from WT PC supernatant (sup): perlecan (PLC, 5 μg/mL) and follistatin (FLT, 500 ng/mL), alone or combined, and vehicle (veh) for 14 days (T14). Scale bar: 100 µm. ( B-D ) Graphs represents the quantification of levels of positive cells for ALP activity, alcian blue, and Oil Red O staining, respectively. All data represent mean ± SD obtained from at least three experiments represented as dots, independently; * p < 0.05; *** p < 0.001; **** p < 0.0001; ns indicates no statistical significance (ANOVA with Tukey’s post-test). ( E ) Quantification of the mRNA expression by qPCR of some genes involved in osteogenesis differentiation. Data show specifically the gene expression levels (expressed as folds over control vehicle and normalized to Actb as the housekeeping reference gene expression) in PDLSCs incubated with PLC and FLT, alone or combined. All data represent mean ± SD obtained from at least three experiments represented as dots, independently; *** p < 0.001; **** p < 0.0001 (ANOVA with Tukey’s post-test). ( F ) Quantification of the mRNA expression by qPCR of some genes involved in inflammatory responses in the microglial cell line BV2 (CT: control) activated with LPS (1 μg/mL) for 24 h (veh) and then incubated with WT PCs sup or KO PCs sup for 24 h after activation (expressed as folds over control non-activated and normalized to Actb and Hrtp1 as housekeeping reference gene expression). Concentrated cultured media (veh) was used as control in activated cells. All data represent mean ± SD obtained from at least four experiments represented as dots, independently; * p < 0.05; ** p < 0.01 (ANOVA with Tukey’s post-test). ( G ) Levels of inflammatory cytokines TNF-α and ( H ) IL-1β secreted by unstimulated microglial cells (CT) or activated with LPS (1 μg/mL) for 24 h (veh) and incubated with WT PCs sup or KO PCs sup for 48 h after stimulation. Concentrated cultured media (veh) was used as control in activated cells. All data represent mean ± SD obtained from at least four experiments represented as dots, independently; * p < 0.05; ** p < 0.01 (ANOVA with Tukey’s post-test).
