Ca2+ signaling in the regulation of dendritic cell functions.
Dendritic cells (DCs) are highly versatile antigen-presenting cells critically involved in both innate and adaptive immunity as well as maintenance of self-tolerance. DC function is governed by Ca(2+) signaling, which directs the DC responses to diverse antigens, including Toll-like receptor ligands, intact bacteria, and microbial toxins. Ca(2+)-sensitive DC functions include DC activation, mat...
متن کاملRecent Advances in T Cell Signaling in Aging
The immune system of mammalian organisms undergoes alterations that may account for an increased susceptibility to certain infections, autoimmune diseases, or malignancies. Well characterized are age related defect in T cell functions and cell mediated immunity. Although it is well established that the functional properties of T cells decrease with age, its biochemical and molecular nature is...
متن کاملCa2+ Signaling in Cytoskeletal Reorganization, Cell Migration, and Cancer Metastasis
Proper control of Ca(2+) signaling is mandatory for effective cell migration, which is critical for embryonic development, wound healing, and cancer metastasis. However, how Ca(2+) coordinates structural components and signaling molecules for proper cell motility had remained elusive. With the advance of fluorescent live-cell Ca(2+) imaging in recent years, we gradually understand how Ca(2+) is...
متن کاملDopamine D2 receptor-activated Ca2+ signaling modulates voltage-sensitive sodium currents in rat nucleus accumbens neurons.
Receptor-mediated dopamine (DA) modulation of neuronal excitability in the nucleus accumbens (NAc) has been shown to be critically involved in drug addiction and a variety of brain diseases. However, the mechanisms underlying the physiological or pathological molecular process of DA modulation remain largely elusive. Here, we demonstrate that stimulation of DA D2 class receptors (D2R) enhanced ...
متن کاملSignaling by protein phosphatases in the nucleus.
The nucleus contains a large variety of protein phosphatases, which function in key processes such as cell-cycle progression, replication, transcription and RNA processing. Here, we review the pleiotropic action of nuclear protein phosphatases and focus in particular on the underlying signaling strategies. It appears that nuclear protein phosphatases can both mediate and antagonize signaling by...
