Regulatory T cells shape the resident memory T cell response to virus infection in the tissues.
Regulatory T cells (Tregs) are well known for their role in dampening the immune responses to self-Ags and, thereby, limiting autoimmunity. However, they also must permit immune responses to occur against foreign infectious agents. Using a mouse model of West Nile virus infection, we examined the role of Tregs in the generation of effector and memory T cell responses in the secondary lymphoid o...
متن کاملCell alkalosis elevates cytosolic Ca2+ in rabbit resident alveolar macrophages.
Disruption of cellular acid-base status alters the host defence functions of alveolar macrophages (m phi). These pH effects might be mediated by pH-sensitive changes in the signalling pathways of the effector functions of m phi. The present study examined the effects of intracellular pH (pH(i)) on the free cytosolic calcium concentration ([Ca(2+)](i)), an important second messenger for cell fun...
متن کاملMacrophages suppress T cell responses and arthritis development in mice by producing reactive oxygen species.
Reduced capacity to produce ROS increases the severity of T cell-dependent arthritis in both mice and rats with polymorphisms in neutrophil cytosolic factor 1 (Ncf1) (p47phox). Since T cells cannot exert oxidative burst, we hypothesized that T cell responsiveness is downregulated by ROS produced by APCs. Macrophages have the highest burst capacity among APCs, so to study the effect of macrophag...
متن کاملIncorporation of T-cell epitopes from tetanus and diphtheria toxoids into in-silico-designed hypoallergenic vaccine may enhance the protective immune response against allergens
Objective(s): New generation of allergy vaccines is capable of promoting the development of protective IgG and blocking the functionality of allergen-specific IgE. We incorporated universal and powerful T-cell epitopes from tetanus and diphtheria toxoids (TD epitope) into recombinant Che a 2, the well-known allergic profilin of Chenopodium album, to determine its immun...
متن کاملIL-17-producing γδ T cells enhance bone regeneration.
Immune responses are crucial not only for host defence against pathogens but also for tissue maintenance and repair after injury. Lymphocytes are involved in the healing process after tissue injury, including bone fracture and muscle damage. However, the specific immune cell subsets and mediators of healing are not entirely clear. Here we show that γδ T cells produce IL-17A, which promotes bone...
