v-SNARE-dependent secretion is required for phagocytosis
Hackam, David J., Rotstein, Ori D., Sjolin, Carola, Schreiber, Alan D., Trimble, William S., Grinstein, Sergio
Phagosomes are generally believed to form by gradual apposition of the plasma membrane of leukocytes onto the surface of invading microorganisms. The internalization of the encapsulated particle is...
Functional Expression of Nramp1 In Vitro in the Murine Macrophage Line RAW264.7
Govoni, Gregory, Canonne-Hergaux, François, Pfeifer, Cheryl G., Marcus, Sandra L., Mills, Scott D., Hackam, David J., ...
Mutations at the Nramp1 locus in vivo cause susceptibility to infection by unrelated intracellular microbes. Nramp1 encodes an integral membrane protein abundantly expressed in the...

The natural resistance associated macrophage protein (Nramp) gene family is composed of two members in mammals, Nramp1 and Nramp2. Nramp1 is expressed primarily in macrophages and mutations at this...

The mechanisms underlying the survival of intracellular parasites such as mycobacteria in host macrophages remain poorly understood. In mice, mutations at the Nramp1 gene (for natural...

Diseases of mucosal inflammation represent important causes of morbidity and mortality, and have led to intense research efforts to understand the factors that lead to their development. It is well...
The development of animal models for the study of necrotizing enterocolitis
Sodhi, Chhinder, Richardson, Ward, Gribar, Steven, Hackam, David J.
Necrotizing enterocolitis (NEC) is the leading cause of death and long-term disability from gastrointestinal disease in preterm infants, and is characterized by acute and chronic intestinal...
One-Dimensional Elastic Continuum Model of Enterocyte Layer Migration
Mi, Qi, Swigon, David, Rivière, Béatrice, Cetin, Selma, Vodovotz, Yoram, Hackam, David J.
Necrotizing enterocolitis is the leading cause of death from gastrointestinal disease in preterm infants. It results from an injury to the mucosal lining of the intestine, leading to translocation of...
Interferon-γ inhibits enterocyte migration by reversibly displacing connexin43 from lipid rafts
Leaphart, Cynthia L., Dai, Shipan, Gribar, Steven C., Richardson, Ward, Ozolek, John, Shi, Xia-hua, ...
Necrotizing enterocolitis (NEC) is associated with the release of interferon-γ (IFN) by enterocytes and delayed intestinal restitution. Our laboratory has recently demonstrated that IFN inhibits...
