The microbiota as instructor and arbiter of immune responses in health and disease
NIH Director's Wednesday Afternoon Lecture Series Dr. Littman ’ s laboratory applies molecular and genetics tools to study how T lymphocytes develop and participate in inflammation and how HIV interacts with the host innate immune system. Dr. Littman isolated the genes for the CD4 and CD8 co-receptors and determined how their expression is regulated and their signaling influences selection of helper and cytotoxic cells. His group discovered that the nuclear receptor ROR  t regulates differentiation of Th17 cells and lymphoid tissue inducer cells and that it can be targeted for autoimmune disease therapy. He and his co...

Oh to be seventeen again: IL-17 signaling in fungal immunity and autoimmune disease
Immunology Interest Group Seminar Series The IL-17 family constitutes a distinct subclass of pro-inflammatory cytokines with unique structures and signaling properties. Signals from IL-17 mediate immunity to extracellular pathogens, particularly the commensal fungus Candida albicans. Conversely, dysregulated IL-17 signal transduction drives pathogenesis in autoimmune conditions, including psoriasis. This talk will discuss both sides of this dual-acting cytokine, from the perspective of IL-17 receptor-induced signal transduction mechanisms. Biography: Dr. Sarah Gaffen received her BS in Biological Sciences from Carnegie Mel...

The multi-faceted role of the IgG glycan
Immunology Interest Group Seminar Series Beyond their role in pathogen neutralization, antibodies mediate pathogen control and clearance via the recruitment of innate immune effector functions including phagocytosis and cytotoxicity but also via the homeostatic regulation of the immune activation. Two modifications to the constant domain of the IgG antibody control this biological activity: 1) the irreversible genomic selection of isotype/subclass and 2) a more subtle alteration in Fc-glycosylation, that together provide instructions to the innate immune system . Because glycosylation alters the affinity of antibodies for ...

Secrets and Lyase: New Roles of S1P Signaling in the Immune System
Immunology Interest Group Seminar Series Sphingosine 1-phosphate (S1P) signaling plays critical roles in the cardiovascular and immune systems. We have recently characterized a mouse that lacks the S1P transporter SPNS2. SPNS2-deficient mice have only a minor reduction in blood S1P and hence grossly normal vascular permeability, but a dramatic reduction in lymph S1P and hence severely disrupted lymphocyte trafficking. These mice have revealed unexpected functions of S1P gradients in positioning immune cells within lymphoid organs, as well as in supporting lymphocyte survival. Dr. Susan Schwab is Associate Professor at the ...

Big Data to individualize management of chronic diseases -- Science Nation
Some chronic conditions, such as the autoimmune disease scleroderma, are especially difficult to treat because patients exhibit highly variable symptoms, complications and treatment responses. The process of finding an effective treatment for an individual can be frustrating for doctors, and ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

Germs, genes, and host defense
Cisca Wijmenga has a long standing interest in understanding the molecular basis of the host immune system and how genetic variation leads to dysregulation of a proper immune response. She is particular interested in diseases associated such an imbalance, in particular celiac disease (a common autoimmune disorder) and candidiasis (a common infectious agent causing sepsis) . Her research group focusing on the regulatory networks of immune cells and their perturbation by genetic variation or physiological stressors like infectious agents or dietary gluten. To this end she founded a functional genomics cohort (LIfeLines Deep)...

Unexpected roles for innate immunity in human Th1 responses
Immunology Interest Group The evolutionary ancient complement system is critical in the protection against infection via direct destruction of pathogens and mobilization and activation of innate and adaptive immune cells. Our current understanding of the complement system is rooted in two key paradigms: Complement operates as a serum (fluid phase) effector system and activation of complement is commonly connected with only a pro-inflammatory outcome – thus, increased or unwanted complement activation is thought to be also the cause of many autoimmune diseases. Recent work, however, indicates that complement activation, e...
