VEGF-C propagates 'onward' colorectal cancer metastasis from liver to lung.

Background: The formation of lung metastasis as part of the progression of colon cancer is a poorly understood process. Theoretically, liver metastases could seed lung metastases.

Methods: To assess the contribution of the liver lymphatic vasculature to metastatic spread to the lungs, we generated murine liver-metastasis-derived organoids overexpressing vascular endothelial growth factor (VEGF)-C.

Onward Spread from Liver Metastases Is a Major Cause of Multi-Organ Metastasis in a Mouse Model of Metastatic Colon Cancer.

Colorectal cancer metastasizes predominantly to the liver but also to the lungs and the peritoneum. The presence of extra-hepatic metastases limits curative (surgical) treatment options and is associated with very poor survival. The mechanisms governing multi-organ metastasis formation are incompletely understood.

Differential cytokine and chemokine expression after ablation vs. resection in colorectal cancer liver metastasis.

Background: Surgical resection remains the main curative treatment for colorectal liver metastases (CRLM). Radiofrequency ablation (RFA) is increasingly employed for small, deep lying or otherwise inoperable lesions. However, RFA can induce pro-tumorigenic effects on residual tumor cells, hereby possibly promoting tumor recurrence.

Tuft cells and fibroblasts promote thymus regeneration through ILC2-mediated type 2 immune response.

The thymus is a primary lymphoid organ that is essential for the establishment of adaptive immunity through generation of immunocompetent T cells. In response to various stress signals, the thymus undergoes acute but reversible involution. However, the mechanisms governing its recovery are incompletely understood.

[HIV as a new diagnose in older patients].

We describe two patients diagnosed with an HIV-1 infection at an older age. In this article we emphasize the importance of knowledge of HIV indicator diseases and keeping a low threshold for HIV-testing.
