SIGLEC9 and infectious meningitis: Two such documented examples include human‐specific pathogens group B streptococcus which engages Siglec‐9 on neutrophils and Siglec‐5 on the amniotic epithelium (Ali et al., 2014; Carlin et al., 2007) and E. coli K‐1 which engages Siglec‐11 on brain microglia, likely suppressing their microbicidal activity during the process of causing meningitis (Schwarz et al., 2017).
