' Medusa' shaped droplets containing liquid crystal molecules
Droplets containing chain-like liquid crystal molecules are spherical at high temperatures, according to findings by University of Pennsylvania researchers. If the chains inside the droplets are of varying lengths, they transform into "pollen," "flowers," "coral," and "Medusa" shapes when the ...This is an NSF Multimedia Gallery item.

Regulating Autoimmunity and Autoinflammation: Cytokine blockade and beyond
Immunonology IG Seminar Richard Siegel's interest in immunology and apoptosis began in the late 1980's at the University of Pennsylvania School of Medicine where he was an M.D., Ph.D. student. Working with Mark Greene and John Reed, he studied the influence of bcl-2 on T cell apoptosis and repertoire selection. He trained in Internal Medicine and Rheumatology at Hospital of the University of Pennsylvania, and moved to the NIH in 1996 to do postdoctoral training with Michael Lenardo in the Laboratory of Immunology in the National Institute of Allergy and Infectious Disease. There he studied apoptosis signaling and the molec...

Law of STAT fives, root orchestrators of lymphocyte homeostasis and function
Immunology Interest Group Seminar Series The transcription factor STAT5 is fundamental to the mammalian immune system. Operating downstream of cytokines and growth factors, it impacts all aspects of lymphocyte biology, from general cellular processes like proliferation and apoptosis, to specialized immunological programs like effector and regulatory T cell differentiation. Genetic studies in humans underscore its widespread influence as mutations of STAT5 or upstream activators manifest varied Alejandro Villarino, NIAMS, NIHimmunological phenotypes including immunodeficiency, autoimmunity and hematological malignancies.

Myeloid-derived Trefoil Factor 2 (TFF2) controls epithelial regeneration at the mucosal interface
Immunology Interest Group Seminar Series Trefoil factor proteins, an enigmatic family of mucosal cytokines, are known to promote tissue repair. Despite being discovered decades ago, not much was known until recently about how Trefoil proteins work. Dr. Herbert ’ s laboratory has discovered that these proteins regulate immune responses in allergic asthma and hookworm infection, and that they trigger the regeneration of epithelial cells. De ’ Broski Herbert is an Associate Professor of Immunology at the University of Pennsylvania School of Veterinary Medicine. He received his B.S. in microbiology from Xavier University i...

Hijacking of immune regulatory mechanisms in lymphoid malignancies
Immunology Interest Group Seminar Series Signalling through the B cell receptor (BCR) is central to the development and maintenance of B cells. In light of the numerous proliferative and survival pathways activated downstream of the BCR, it comes as no surprise that malignant B cells would co-opt this receptor to promote their own growth and survival. However, direct evidence for BCR signalling in human lymphoma has only come to light recently. Roles for antigen-dependent and antigen-independent, or tonic, BCR signalling have now been described for several different lymphoma subtypes. Furthermore, correlative data implicat...
