  abstract  = {Die Aktivierung der T Zelle bedarf der spezifischen Interaktion zwischen T Zelle und Antigen-pr{\"a}sentierender Zelle unter Ausbildung einer engen Anlagerung beider Zellmembranen („immunologische Synapse") f{\"u}r Rezeptoren-Interaktionen und konsekutive Signaltransduktion. In dreidimensionaler Kollagenmatrix zeigte sich ein stereotypes, dynamisches Muster bei der Interaktion zwischen CD45RO-positiven humanen T Zellen und antigenpr{\"a}sentierenden dendritischen Zellen. i) Die Kontaktaufnahme wurde stets {\"u}ber das Leading edge der T Zelle initiiert. ii) Beim dynamischen Kontakt wanderte die T Zelle polarisiert, mit vielen Richtungs{\"a}nderungen und mit reduzierter Geschwindigkeit auf der DC-Oberfl{\"a}che, nur unterbrochen von kurzen Stopp- und Abrundungsphasen. Der Uropod der T Zelle stand w{\"a}hrend der dynamischen Kontakts in kontinuierlicher Verbindung zur DC. iii) Die Losl{\"o}sung der T Zelle von der DC war ein aktiver Prozess, der durch Interaktion der Vorderfront der T Zelle zu benachbarten Kollagenfasern eingeleitet wurde, gefolgt von der L{\"o}sung des Zellk{\"o}rpers und des Uropods. Alternativ wurden Kontakte durch Uropod-mediierte Retention der T Zelle auf der DC-Oberfl{\"a}che verl{\"a}ngert. Zur dynamischen molekularen Charakterisierung der Kontaktfl{\"a}che wurde eine Methode zur Darstellung von Lipid-Rafts an lebenden Zellen in der 3D ECM mit BTRITC etabliert. Die Ergebnisse zeigen ein neues 3-Schritt-Konzept dynamischer und produktiver Interaktionen zwischen T Zelle und DC in vitro. Die assymetrische Kontaktzone impliziert distinkte Funktionen von Vorderfront und Uropod der T Zelle und definiert eine neuartige dynamische Kontaktform f{\"u}r die Signal{\"u}bertragung zwischen beweglichen Zellen.},

  abstract  = {IgG3 is the IgG subclass with the strongest effector functions among all four IgG subclasses and the highest degree of allelic variability among all constant immunoglobulin genes. Due to its genetic position, IgG3 is often the first isotype an antibody switches to before IgG1 or IgG4. Compared with the other IgG subclasses, it has a reduced half-life which is probably connected to a decreased affinity to the neonatal Fc receptor (FcRn). However, a few allelic variants harbor an amino acid replacement of His435 to Arg that reverts the half-life of the resulting IgG3 to the same level as the other IgG subclasses. Because of its functional impact, we hypothesized that the p.Arg435His variation could be associated with susceptibility to autoantibody-mediated diseases like pemphigus vulgaris (PV) and bullous pemphigoid (BP). Using a set of samples from German, Turkish, Egyptian, and Iranian patients and controls, we were able to demonstrate a genetic association of the p.Arg435His variation with PV risk, but not with BP risk. Our results suggest a hitherto unknown role for the function of IgG3 in the pathogenesis of PV.},

  abstract  = {The COVID-19 pandemic caused by SARS-CoV-2 has far-reaching direct and indirect medical consequences. These include both the course and treatment of diseases. It is becoming increasingly clear that infections with SARS-CoV-2 can cause considerable immunological alterations, which particularly also affect pathogenetically and/or therapeutically relevant factors. Against this background we summarize here the current state of knowledge on the interaction of SARS-CoV-2/COVID-19 with mediators of the acute phase of inflammation (TNF, IL-1, IL-6), type 1 and type 17 immune responses (IL-12, IL-23, IL-17, IL-36), type 2 immune reactions (IL-4, IL-13, IL-5, IL-31, IgE), B-cell immunity, checkpoint regulators (PD-1, PD-L1, CTLA4), and orally druggable signaling pathways (JAK, PDE4, calcineurin). In addition, we discuss in this context non-specific immune modulation by glucocorticosteroids, methotrexate, antimalarial drugs, azathioprine, dapsone, mycophenolate mofetil and fumaric acid esters, as well as neutrophil granulocyte-mediated innate immune mechanisms. From these recent findings we derive possible implications for the therapeutic modulation of said immunological mechanisms in connection with SARS-CoV-2/COVID-19. Although, of course, the greatest care should be taken with patients with immunologically mediated diseases or immunomodulating therapies, it appears that many treatments can also be carried out during the COVID-19 pandemic; some even appear to alleviate COVID-19.},
