Published in Nature (2023), Kruse et al. (Tüting lab) demonstrate that adoptively transferred CD4+ T cells alone—but not CD8+ T cells—can eradicate melanoma tumors completely lacking both MHC class I and II expression. These findings challenge the current paradigm of cancer immunotherapy, which predominantly focuses on CD8+ cytotoxic T cells whose effectiveness is limited by MHC loss and immunosuppressive TME. Historically viewed merely as ‘helper’ cells, CD4+ T cells instead have a critical yet underappreciated capacity for antitumor immunity independent of CD8+ cells. Intriguingly, CD4+ T cells do not directly infiltrate tumors in the same way CD8+ T cells do. Rather, they profoundly reshape the tumor immune landscape by recruiting and functionally reprogramming myeloid cells. These myeloid cells mature into potent interferon-activated APCs and robust iNOS-expressing tumoricidal effectors. This study uncovers exciting therapeutic opportunities by revealing the potential of CD4+ T cells to complement CD8+ T cells and NK cells, paving the way for innovative strategies against immune-evasive cancers.

The time for putin's friends in Hungary and Serbia is over. Budapest (Video 1) A huge rally of the opposition, which is already ahead of Orban in the polls, is calling for early elections. Peter Magyar explains: Spring is coming to Hungary, together we will end Orban's winter. Belgrade (Video 2) The most massive protest – according to various estimates, up to 1 million people took to the streets and demanded Vucic's resignation. The presidential residence is surrounded by special forces and troops. Hungary and Serbia are Moscow's most important allies in Europe. But it seems as if their "stability" is starting to crack.

Very significant statements by President Macron: We cannot forget that Russia began to invade Ukraine in 2014 and we then negotiated a ceasefire in Minsk. And the same Russia did not respect this ceasefire. Today, we can no longer take Russia's word for it. 1/5⬇️
