The number of memory phenotype CD8 T cells increases dramatically with aging in both humans and mice. However, the mechanism for this is unknown. The prevailing hypothesis is that memory T cells accumulate with aging as a result of lifelong antigenic

Cysteine-cysteinyl chemokine receptor 4 (CCR4) is expressed by a variety of T-cell subsets and leukocytes. This study examined the participation of CCR4 in response to pulmonary infection with Mycobacterium bovis Bacille-Calmette-Guerin (BCG). Consti

Impaired pulmonary immunity in the aged is poorly understood. Lymph node recirculation of CD4+ T cells is important for adaptive immunity and depends on CD62L and CCR7. We compared circulatory capacity of CD4+ T cells from young and aged mice in vivo

As potent suppressors of immune responses to self- and foreign-antigens, Foxp3+ Treg cells are suspected to be involved in immunosuppression leading to cancer, neurodegeneration and infection. Since ageing is associated with increased incidence of th

CCR4 is purported to be a Th type 2 (Th2) cell-biased receptor but its functional role is unclear. Recent studies suggest that chemokine receptor expression and function are more complex in vivo and raise doubts regarding restricted CCR4 expression b

The contribution of inducible costimulatory molecule (ICOS) to Th1 and Th2 cell-mediated immune responses was examined in well-defined pathogen antigen-elicited models of cell-mediated granuloma formation. Th1 and Th2 granulomas were respectively ind

Dendritic cell (DC) recruitment is a hallmark event in antigen (Ag)-challenged lungs. We previously reported models for analyzing DC migration and activation in the lung after Th1- or Th2-eliciting pathogen Ag-bead challenge. To determine the role of

Granulomas are innate sequestration responses that can be modified by superimposed acquired immune mechanisms. The present study examined the innate stage of pulmonary granuloma responses to bead-immobilized Th1- and Th2-inducing pathogen antigens (A

Chemokine receptor transcripts were de- fined among CD4 T cells in lymph nodes of mice with type-1 and type-2 inflammation, respectively, elicited by mycobacterial and schistosomal Ag. CXCR3 and CCR6 transcripts were biased to type-1, and CCR4 transc

Monocyte chemotactic protein-3 (MCP-3/CCL7) has potent eosinophil chemoattractant properties. The present study determined its relative contribution to the formation of Th2 cytokine-mediated (type-2) eosinophil-rich interstitial lung granulomas induc
