Measurement of Dipeptidylpeptidase Activity in vitro and in vivo
[Abstract] Dipeptidylpeptidases (DPPs) are serine proteases, which cleave small proteins and peptides possessing a proline or an alanine in the second position of their N-terminus. Among the members of this family, dipeptidylpeptidase 4 (DPP4) is constitutively expressed in the extracellular space. DPP4 is found at the surface of many hematopoietic and ...

[Abstract] The NLRP3 (NLR family, Pyrin domain containing 3) inflammasome is a multiprotein complex comprised of NLRP3, pro-caspase-1, the adaptor protein apoptosis-associated speck-like protein containing a CARD (ASC), and the protein kinase NIMA related kinase 7 (NEK7) (Shi et al., 2016; He et al., 2016; Schmid-Burgk et al., ...

[Abstract] Extracellular tumor material including exosomes, microvesicles and apoptotic tumor debris may help cancers invade new organs. Enhancing the removal of extracellular tumor material by immune cells represents a novel immunotherapy approach for preventing cancer metastasis. This protocol quantifies the uptake and removal of extracellular tumor ...
In vivo Imaging of Tumor and Immune Cell Interactions in the Lung
[Abstract] Immunotherapy has demonstrated great therapeutic potential by activating the immune system to fight cancer. However, little is known about the specific dynamics of interactions that occur between tumor and immune cells. In this protocol we describe a novel method to visualize the interaction of tumor and immune cells in the lung of live mice, ...
Measurement of mRNA Decay in Mouse Embryonic Fibroblasts
[Abstract] mRNA stability control is a critical step in the post-transcriptional regulation of gene expression. Actinomycin D, an antibiotic initially used as an anti-cancer drug, has turned out to be a convenient tool for studying the turnover rates of transcripts in cells, due to its inhibition of mRNA synthesis. Here, we describe a protocol for the ...
