Heat Killed Streptococcus pneumoniae

Streptococcus pneumoniae, a Gram positive bacterium, is the principal etiologic agent of bacterial meningitis in adults.

Heat-killed Streptococcus pneumoniae  (HKSP) induce activation of NF-κB in a TLR2- and CD14-dependent manner [1].

TLR2 has been shown to play an important role in the protein- and polysaccharide-specific type 1 IgG isotype response following immunization with HKSP [2].
