<jats:p>
The Reg3 protein family, including the human member designated pancreatitis-associated protein (PAP), consists of secreted proteins that contain a C-type lectin domain involved in carbohydrate binding. They are expressed by intestinal epithelial cells. Colonization of germ-free mice and intestinal infection with pathogens increase the expression of Reg3g and Reg3b in the murine ileum. Reg3g is directly bactericidal for Gram-positive bacteria, but the exact role of Reg3b in bacterial infections is unknown. To investigate the possible protective role of Reg3b in intestinal infection, Reg3b knockout (Reg3b
<jats:sup>−/−</jats:sup>
) mice and wild-type (WT) mice were orally infected with Gram-negative
<jats:named-content content-type="genus-species">Salmonella enteritidis</jats:named-content>
or Gram-positive
<jats:named-content content-type="genus-species">Listeria monocytogenes</jats:named-content>
. At day 2 after oral
<jats:named-content content-type="genus-species">Listeria</jats:named-content>
infection and at day 4 after oral
<jats:named-content content-type="genus-species">Salmonella</jats:named-content>
infection, mice were sacrificed to collect intestinal and other tissues for pathogen quantification. Protein expression of Reg3b and Reg3g was determined in intestinal mucosal scrapings of infected and noninfected mice. In addition,

<jats:named-content content-type="genus-species">Listeria</jats:named-content>
