'Sepsis is a leading cause of death in the Western world and can be associated with failure of the hypothalamic-pituitary-adrenal axis. A coordinated response of the adrenal and immune system is of vital importance for survival during sepsis. Within the immune response, Toll-like receptors (TLRs) play a crucial role by ... More
Osteopontin deficiency impairs wear debris-induced osteolysis via regulation of cytokine secretion from murine macrophages.

To investigate the molecular mechanisms underlying particle-induced osteolysis, we focused on osteopontin (OPN), a cytokine and cell-attachment protein that is associated with macrophage chemoattractant and osteoclast activation. We compared OPN protein levels in human periprosthetic osteolysis tissues with those in osteoarthritis (OA) synovial tissues. To investigate the functions of OPN ... More

Respiratory tract infections result in wheezing in a subset of patients. Mycoplasma pneumoniae is a common etiologic agent of acute respiratory infection in children and adults that has been associated with wheezing in 20-40% of individuals. The current study was undertaken to elucidate the host-dependent pulmonary and immunologic response to ... More
Intranasal interleukin-12 therapy inhibits Mycoplasma pneumoniae clearance and sustains airway obstruction in murine pneumonia.

Mycoplasma pneumoniae is a leading cause of pneumonia and is associated with asthma. Evidence links M. pneumoniae respiratory disease severity with interleukin-12 (IL-12) concentrations in respiratory secretions. We evaluated the effects of IL-12 therapy on microbiologic, inflammatory, and pulmonary function indices of M. pneumoniae pneumonia in mice. BALB/c mice were ... More
Neisseria meningitidis PorB, a Toll-like receptor 2 ligand, improves the capacity of Francisella tularensis lipopolysaccharide to protect mice against experimental tularemia.
Francisella tularensis causes severe pneumonia that can be fatal if it is left untreated. Due to its potential use as a biological weapon, research is being conducted to develop an effective vaccine and to select and study adjuvant molecules able to generate a better and long-lasting protective effect. PorB, a ... More
