On Friday 9 January 2026 at 9:30 AM at the UW Faculty of Physics (Pasteura 5, Warsaw; room 1.40) we are hosting a seminar, during which Tomasz Lipniacki (IPPT PAN) will give a talk Antagonism between viral infection and innate immunity at the single-cell level Abstract Authors: Frederic Grabowski, Marek Kocha?czyk, Zbigniew Korwek, Maciej Czerkies, Wiktor Prus, Tomasz Lipniacki (Institute of Fundamental Technological Research, Polish Academy of Sciences) When infected with a virus, cells may secrete interferons (IFNs) that prompt nearby cells to prepare for upcoming infection. Reciprocally, viral proteins often interfere with IFN synthesis and IFN-induced signaling. We modeled the crosstalk between the propagating virus and the innate immune response using an agent-based stochastic approach. By analyzing immunofluorescence microscopy images we observed that the mutual antagonism between the respiratory syncytial virus (RSV) and infected A549 cells leads to dichotomous responses at the single-cell level and complex spatial patterns of cell signaling states. Our analysis indicates that RSV blocks innate responses at three levels: by inhibition of IRF3 activation, inhibition of IFN synthesis, and inhibition of STAT1/2 activation. In turn, proteins coded by IFN-stimulated (STAT1/2-activated) genes inhibit the synthesis of viral RNA and viral proteins. The striking consequence of these inhibitions is a lack of coincidence of viral proteins and IFN expression within single cells.

Using the Euler?Bernoulli (elastica) description linearized about a straight configuration of arbitrary orientation, we show that the 3D stability problem can be reduced to a universal spectral problem governed by an orientation-dependent combination of the elastoviscous number and the shear geometry. Building on earlier in-plane eigenmodes, we solve the 3D eigenproblem and propose a simple analytic approximation of the unstable eigenfunctions as Gaussian wave packets. This yields the central scaling result: for highly flexible filaments, the characteristic wavenumber of the most unstable mode grows proportionally to the square root of this elastoviscous measure. Finally, we validate the predicted eigenshapes by numerical simulations of finite-thickness filaments using a bead model and the HYDROMULTIPOLE codes. The talk is based on our paper: P. Sznajder, P. Zdybel, L. Liu, and M. L. Ekiel-Je?ewska, Phys. Rev. E 110, 025104 (2024). We warmly welcome everyone to attend the talk and the Soft Matter Coffee Break after the seminar, held in room 2.63 (2nd floor).
