Burn induces an immunopathological response involving multiple immune cell types that includes γδ T-cells. Nonetheless, the role of γδ T-cells at the wound site after burn is not clearly defined. Wild type and γδ T-cell receptor deficient (δ TCR(-/-)) mice were subjected to a major burn or sham procedure. At 1-7 d thereafter, skin samples were collected and(More)
Major burns induce immune complications, which are associated with myeloid cell activation by ill-defined mechanisms. Although γδ T cells have been shown to be important in postinjury inflammation and wound healing, their role in the regulation of myeloid cells remains unknown. To study this, wild-type (WT) and γδ T cell-deficient (δTCR) mice were subjected(More)
Murine polymicrobial sepsis is associated with a sustained reduction of dendritic cell (DC) numbers in lymphoid organs and with a dysfunction of DC that is considered to mediate the chronic susceptibility of post-septic mice to secondary infections. We investigated whether polymicrobial sepsis triggered an altered de novo formation and/or differentiation of(More)
BACKGROUND Gamma delta T-cells have been shown to be important to the early immunoinflammatory response to injury, independent of infection. This unique T-cell population acts to regulate cell trafficking and the release of cytokines and growth factors. We propose this sterile inflammatory response is in part associated with damage associated molecular(More)
UNLABELLED Burn is associated with profound inflammation and activation of the innate immune system in multiple organ beds, including the lung. Similarly, toll-like receptors (TLR) are associated with innate immune activation. Nonetheless, it is unclear what impact burn has on TLR-induced inflammatory responses in the lung. METHODS Male C57BL/6 mice were(More)
Aging is an important and critical factor that contributes to the clinical outcome of burn patients. The very young and the elderly are more likely to succumb after major burn as compared to their adult counterparts. With the aging population, improved understanding of the mechanisms underlying age-associated complications after burns becomes even more(More)
OBJECTIVE Systemic tacrolimus therapy has been shown to protect against lung ischemia-reperfusion injury in animal models. We sought to investigate on a functional and cellular level if inhaled nanoparticle tacrolimus administered to the donor lung before procurement could similarly attenuate ischemia-reperfusion injury after lung transplant. METHODS An(More)
The development of immunosuppression during polymicrobial sepsis is associated with the failure of dendritic cells (DC) to promote the polarization of T helper (Th) cells toward a protective Th1 type. The aim of the study was to test potential immunomodulatory approaches to restore the capacity of splenic DC to secrete interleukin (IL) 12 that represents(More)
Burn and toll-like receptors (TLR) are associated with innate immune system activation, but the impact of burn on TLR-induced inflammation responses by circulating leukocytes is unknown. To study this, C57BL/6 mice were subjected to burn (3(rd) degree, 25% TBSA) or sham procedure and 1-7 days later blood was collected. Whole blood cell suspensions were(More)
Gamma delta T-cells have been shown to be important in the early immunoinflammatory response to injury, which can be independent of infection. This sterile inflammatory response is believed to be, in part, associated with danger-associated molecular patterns (DAMPs). Mitochondrial DAMPs (MTDs) have been shown to be important in trauma-induced neutrophil(More)
