Cerebral small vessel disease (CSVD) primarily affects small perforating arterioles and is characterized by lacunes, cerebral microbleeds (CMBs), cortical superficial siderosis, deep white matter hyperintensities (DWMH), enlarged perivascular spaces, and microinfarcts., , CSVD contributes to roughly a quarter of ischemic strokes, serves as a major cause of intracerebral hemorrhage, and is linked to worse poststroke outcomes, cognitive impairment and dementia, depression, gait/mobility issues, and vascular dementia. Despite associations with traditional risk factors such as hypertension, arteriosclerosis, advanced age, lipohyalinosis, male sex and chronic kidney disease, CSVD in normotensive individuals highlights gaps in pathophysiology. Imaging studies have further indicated that the progression of CSVD can be nonlinear and may accelerate over time, suggesting a highly dynamic nature of its disease course. To manage CSVD, early risk factor intervention should be strengthened, centring on endothelial dysfunction and multidimensional phenotypic analysis, to provide a more scientific basis for prevention and treatment strategies. In recent years, infectious and microbial factors have progressively entered the research landscape of cerebrovascular diseases. The oral cavity serves as a significant microbial reservoir in the human body, with nearly 700 bacterial species identified as capable of colonizing oral ecological niches, while also representing a common source of chronic low-grade inflammation. Its amenability to routine intervention has led to its consideration as a noteworthy, controllable upstream entry point for systemic vascular pathologies. Invasive dental procedures and certain everyday oral activities can induce transient bacteraemia, thereby providing a potential hematogenous pathway for oral bacteria or their components to interact with the systemic vasculature. Among these, species represent notable members of the oral microbiota that exhibit a propensity for transient hematogenous translocation following mucosal barrier disruption., , , , Accumulating evidence suggests that their potential systemic relevance may be dictated not by gross genus-level abundance, but by specific molecular virulence traits. Collagen-binding proteins represent pivotal virulence factors widely expressed across members of the genus , which fundamentally dictate their localized tissue adherence and pathogenic potential., , For instance, the CpA protein in the CbpA protein in and the Cbp40 protein in have all been characterized as critical determinants enabling bacteria to interact with the host extracellular matrix. Building upon this generic streptococcal virulence trait, this study specifically focused on the Cnm protein, a distinct collagen-binding protein originally identified in specific () strains. The Cnm protein exhibits broad binding affinity to types I and IV collagen as well as laminin. In the context of cerebrovascular remodelling – where extracellular matrix components like collagen often become exposed or altered – circulating -positive streptococci might theoretically exploit these compromised sites, potentially contributing to localized endothelial stress or blood-brain barrier impairment.
