Linking TCR Signaling to Variations in Gene Expression
The control of T cell lineage development in the thymus and T cell differentiation pathways following activation are strongly influenced by T cell receptor (TCR) signaling. Yet the details of how variations in the strength of TCR stimulation produce distinct gene expression programs is poorly understood. Dr. Berg ’ s work has focused on understanding the contribution of ITK to this process. ITK is a Tec family tyrosine kinase known to modulate ‘ TCR signal strength ’ ; biochemically, ITK phosphorylates and activates the enzyme phospholipaseC- γ 1. Using a combination of transcription factor activation assays, genomi...

NIDCR Clinical Research Fellowship Grand Round: The temporomandibular Joint (TMJ)
The temporomandibular joint (TMJ) is the synovial joint of craniofacial complex and is critical for dental occlusion, mastication, and speech. TMJ trauma and diseases, such as osteoarthritis, are debilitating and compromise quality of life. Current TMJ treatments are two-fold, involving either palliative care or invasive total joint replacement surgeries. There are no minimally invasive, regenerative TMJ therapies. We have identified TMJ-specific fibrocartilage stem cells that self-organize and regenerate cartilage, fat and vascularized bone. Here we define heterogeneous populations of TMJ fibrocartilage stem cells and the...

IIG Seminar - Type I interferon induction and exhaustion upon viral infection
Dr. Zuniga ’ s laboratory discovered that, in response to a viral infection, systemic type I interferons (IFN-I) are initially elevated but are subsequently and rapidly silenced despite continuous pathogen replication. They showed that there is an IFN-I refractory (or exhaustion) phase, during which the infected host fails to elevate IFN-I upon secondary unrelated infections, explaining delayed viral control and enhanced susceptibility to opportunistic infections. Dr. Zuniga will present their recent work on the mechanisms underlying the initial IFN-I elevation and its subsequent, rapid, suppression after viral infection...

Human antibody responses to SARS-CoViD-2
NIH Director's Wednesday Afternoon Lecture Series Annual William E. Paul Lecture – – Dr. Nussenzweig ’ s laboratory studies the molecular aspects of the immune system ’ s innate and adaptive responses using a combination of biochemistry, molecular biology, and genetics. For work on adaptive immunity, he focuses on B lymphocytes and antibodies to HIV-1, while his studies of innate immunity focus on dendritic cells. His work is leading to new antibody-based therapies for infections by HIV and the novel SARS-CoV-2 coronavirus, among other viruses.For more information go tohttps://oir.nih.gov/wals/about-walsAir date: 1...

Translating Thought into Blood Flow in the Brain: Capillaries as Sensors of Neural Activity
NIH Director's Wednesday Afternoon Lecture Series The Nelson laboratory ’ s research interests include elucidating the mechanisms by which cerebral blood flow is controlled to meet the diverse and ever-changing demands of active neurons and how these mechanisms are disrupted in small vessel disease (SVD) — a major cause of stroke and dementia. Dr. Nelson and colleagues have unraveled many of the major mechanisms that control cerebrovascular function, including the discovery of local calcium signals ( “ sparks ” ), which counter-intuitively oppose vasoconstriction. They have recently shown that brain capillaries ac...

The Case for BK Polyomavirus as a Cause of Bladder Cancer
NCI ’ s Center for Cancer Research (CCR) Grand Rounds Dr. Buck ’ s lab studies polyomaviruses. A great majority of healthy adults chronically shed polyomavirus virions in their urine and from the surface of their skin. Although these lifelong infections generally aren't known to cause symptoms in healthy individuals, under conditions of immune impairment polyomaviruses can cause disease. For example, BK polyomavirus (BKV) causes kidney and bladder damage in organ transplant patients, while its close relative JCV causes a lethal brain disease in patients on immunosuppressive therapies and in individuals suffering from ...
