Neutrophils are the main inflammatory cell present in lesions
involving the central nervous system (CNS) during human and murine
listeriosis. In this study, administration of the neutrophil-depleting monoclonal antibody RB6-8C5 during experimental murine listeriosis facilitated the multiplication of Listeria monocytogenes in
the CNS. These data suggest that neutrophils play a key role in
eliminating bacteria that gain access to the CNS compartment. In
addition, we provide evidence that their migration into the CNS may be
necessary for the subsequent recruitment of macrophages and activated lymphocytes.
