obligatory for T cell activation and argue for a re-examination of the two-signal theory as the basis for decisions between tolerance and activation.doi... AV Gett,PD Hodgkin - 《Nature Immunology》 被引量: 400发表: 2000年 A two-phase model of B-cell activation. The current paradigm of ...
1A). This model of T-cell activation is referred to as the two-signal model with a tertiary signal directing the type of immune activation. The initial signal comes from interactions between the T-cell receptor (TCR) on naïve CD4 or CD8 T cells and processed antigenic peptides via the ...
T-cell activation requires costimulation in addition to the antigen-specific signal. Recent results suggest that distinct costimulatory molecules can specifically activate different types of T-cell response.doi:10.1016/S0960-9822(95)00175-8Sylvie Guerder...
Figure 3: Is a 'two-signal' model of T cell activation still tenable? Signals emanating from the TCR (or the BCR) and the optional signals originating from a vast array of cell surface context detectors converge on intracytoplasmic coincident detectors. From: Innate and adaptive immunity: ...
7c). Taken together, our findings suggest that circulating DCs rapidly migrate to lymphedematous tissues, become activated, and then traffic to regional lymph nodes where two-signal interaction with T cells is necessary for T cell differentiation. CD4+ T cells inhibit lymphatic pumping via ...
T Cell Activation When a T cell encounters a recognizable APC, the naïve cell receives a signal to mature. There are three types of signals: TCR, BCR, and cytokine signals. If a cell receives all three signals, it will mature into an effector cell. If a cell only receives one of th...

Janus kinase/signal transducer and activator of transcription signalling. Such chimeric cytokine receptors, which can be generated for common γ-chain receptors, interleukin-10 and -12 receptors, enabled T cells to survive cyt...
EGFR is upregulated through STAT5 signal transduction after the activation of Treg cells. The inhibition ability of Treg cells after binding to Areg may be improved by secreting exosomes containing immunosuppressive RNA [51], while Treg cells without Areg will fail to exercise their function of ...
