Leukemic cell-secreted interleukin-9 suppresses cytotoxic T cell-mediated killing in chronic lymphocytic leukemia

G. Boncompagni, V. Tatangelo, L. Lopresti, C. Ulivieri, N. Capitani, C. Tangredi, F. Finetti, G. Marotta, F. Frezzato, A. Visentin, S. Ciofini, A. Gozzetti, M. Bocchia, D. Calzada-Fraile, N. B. Martin Cofreces, , C. T. Baldari

This study shows that IL-9 secreted by leukemic cells suppresses CTL-mediated killing in CLL by increasing PD-1 expression and impairing immune synapse formation.

Polo-like kinase 1 regulates immune synapse assembly and cytotoxic T cell function by driving microtubule dynamics

F. Zevolini, A. Onnis, R. Khazen, S. Mueller, G. Marotta, S. Valiltutti, F. Finetti, C. Baldari

This study shows that Polo-like kinase 1 (PLK1) is essential for immune synapse (IS) assembly and cytotoxic T cell function by regulating microtubule dynamics during IS formation.

Human colorectal cancer: upregulation of the adaptor protein Rai in TILs leads to cell dysfunction by sustaining GSK-3 activation and PD-1 expression

T. Montecchi, G. Nannini, D. De Tommaso, C. Cassioli, F. Coppola, M. N. Rigressi, F. Carraro, A. Naldini, A. Taddei, G. Marotta, A. Amedei, C. T. Baldari, C. Ulivieri

This study identifies Rai as a novel HIF-1-responsive gene upregulated in CRC TILs, which promotes T cell exhaustion by sustaining GSK-3 activation and PD-1 expression.

SARS-CoV-2 Spike protein suppresses CTL-mediated killing by inhibiting immune synapse assembly

A. Onnis, E. Andreano, C. Cassioli, E. Pantano, V. Abbiento, G. Marotta, R. Rappuoli, C. T. Baldari

This study shows SARS-CoV-2 Spike protein inhibits CTL immune synapse formation by binding ACE2, reducing target cell killing.
