However, there is a lack of literature investigating the relationship between the gut microbiota and blood metabolites in cerebral infarction.

However, the proteinaceous mediators of its adhesion remain largely elusive. The P35 family lipoprotein, encoded by the mpl gene, is a prominent surface lipoprotein of M. penetrans. Here, we investigated the role of P38, a member of the P35 family, in the adhesion of M. penetrans to human urothelial cells (SV-HUC-1). We expressed and purified recombinant P38 (rP38) and confirmed its localization using Western blot. Adhesion assays, adhesion inhibition assays, and adhesion competition assays were performed to evaluate the adhesive properties of rP38 and M. penetrans. Our findings indicated that P38 localizes to the cell membrane of M. penetrans. Both rP38 and M. penetrans adhered to SV-HUC-1 cells, with optimal adhesion observed at 60 μg/mL for rP38 and 1 × 10⁷ CCU (Colony-Changing Units)/mL for M. penetrans. Anti-rP38 serum partially inhibited M. penetrans adhesion to SV-HUC-1 cells, and rP38 competed with M. penetrans for binding to SV-HUC-1 cells.
