Molecular Imaging of Tumor-Infiltrating Lymphocytes in Living Animals Using a Novel mCD3 Fibronectin Scaffold.

The interaction between cancer cells and immune cells in the tumor microenvironment (TME) plays a crucial role in determining tumor growth, metastasis, and response to treatment. Tumor-infiltrating lymphocytes (TILs) in TME could be a predictive marker for treatment response in various therapeutic interventions, including chemotherapy and immunotherapy. Thus, imaging the tumor immune microenvironment is important for selecting the optimal treatment strategies in cancer therapy.

A mutant fitness compendium in Bifidobacteria reveals molecular determinants of colonization and host-microbe interactions.

Bifidobacteria commonly represent a dominant constituent of human gut microbiomes during infancy, influencing nutrition, immune development, and resistance to infection. Despite interest as a probiotic therapy, predicting the nutritional requirements and health-promoting effects of Bifidobacteria is challenging due to major knowledge gaps. To overcome these deficiencies, we used large-scale genetics to create a compendium of mutant fitness in ().

The dialectics of cancer: A theory of the initiation and development of cancer through errors in RNAi.

The recent discoveries of the RNA-mediated interference system in cells could explain all of the known features of human carcinogenesis. A key, novel idea, proposed here, is that the cell has the ability to recognise a mutated protein and/or mRNA. Secondly, the cell can generate its own short interfering RNA (siRNA) using an RNA polymerase to destroy mutated mRNA, even when only a single base pair in the gene has mutated.
