Background and Purpose—Macrophage inflammatory protein (MIP)-1 is a well-characterized monocyte chemoattractant; its role in regulating monocyte and microglial recruitment and activation in the injured neonatal brain is unknown. We evaluated the impact of acute hypoxic-ischemic (HI) brain injury on the expression of MIP-1 in neonatal rat brain. Methods—To elicit forebrain ischemic injury, 7-day...

Chemokines are important mediators in the development of inflammation. Our previous work demonstrated that an oxidative stress can up-regulate mRNA expression of a CC chemokine macrophage inflammatory protein (MIP)-1alpha in rat alveolar macrophages. In the present study, we further investigate whether an oxidative stress can regulate the gene expression of a related CXC chemokine MIP-2, involv...

The aim of this work was to investigate the role of chemokines in proliferation and migration of tongue squamous cell carcinoma (TSCC). Out of the 80 cytokines surveyed by a human cytokine antibody array, three chemokines, macrophage inflammatory protein-3α (MIP-3α), macrophage inflammatory protein-1β (MIP-1β), and interferon gamma-induced protein 10 (IP-10), showed elevated expression in TSCC ...

Recent data have implicated macrophage inflammatory protein-1alpha (MIP-1alpha) in multiple myeloma (MM)-associated osteolysis. However, it is unclear whether the chemokine's effects are direct, to enhance osteolysis, or indirect and mediated through a reduction in tumor burden, or both. It is also unclear whether MIP-1alpha requires other factors such as receptor activator of nuclear factor-ka...

Platelet-activating factor (PAF) is a potent endogenous mediator of bowel inflammation. It activates neutrophils that are needed to initiate the inflammatory response. Macrophage inflammatory protein-2 (MIP-2), a critical C-X-C chemokine secreted by macrophages and epithelial cells, is a potent chemoattractant for neutrophils. Whereas MIP-2 has been previously shown to mediate the injury in var...

Transforming growth factor beta 1 (TGF-beta 1) and macrophage inflammatory protein 1 alpha (MIP-1 alpha) have recently been identified as potent inhibitors of hemopoietic stem cell proliferation. From previous studies, these molecules appear to have similar functions in the control of stem cell proliferation. This study was designed to investigate the relationship, if any, between these two neg...

BACKGROUND/AIMS Macrophage inflammatory protein-2 (MIP-2), one of the CXC chemokines, is involved in the recruitment of neutrophils in several tissue injuries. In this study, we investigated the role of MIP-2 in concanavalin A (Con A)-induced liver injury in mice. METHODS Liver injury was induced by intravenous injection of Con A (15 mg/kg) and plasma alanine aminotransferase (ALT), MIP-2 lev...

BACKGROUND Model-based iterative reconstruction (MBIR) reduces image noise and improves image quality (IQ) but its influence on post-processing tools including maximal intensity projection (MIP) and minimal intensity projection (mIP) remains unknown. PURPOSE To evaluate the influence on IQ of MBIR on native, mIP, MIP axial and coronal reformats of reduced dose computed tomography (RD-CT) ches...

BACKGROUND Pregnant women and infants are particularly vulnerable to malaria. National malaria in pregnancy (MIP) programs in Malawi, Senegal, and Zambia were reviewed to identify promising strategies that have helped these countries achieve relatively high coverage of MIP interventions as well as ongoing challenges that have inhibited further progress. METHODS We used a systematic case study...
