In vitro STING Activation with the cGAMP-STINGΔTM Signaling Complex
[Abstract] Activating the STING (stimulator of interferon genes) signaling pathway via administration of STING agonist cyclic GMP-AMP (cGAMP) has shown great promise in cancer immunotherapy. While state-of-the-art approaches have predominantly focused on the encapsulation of cGAMP into liposomes or polymersomes for cellular delivery, we discovered that the ...
Generation and Testing of Fluorescent Adaptable Simple Theranostic (FAST) Proteins
[Abstract] This protocol provides a step-by-step method to create recombinant fluorescent fusion proteins that can be secreted from mammalian cell lines. This builds on many other recombinant protein and fluorescent protein techniques, but is among the first to harness fluorescent fusion proteins secreted directly into cell culture supernatant. This opens ...
Measurement of Protein-Protein Interactions through Microscale Thermophoresis (MST)
[Abstract] The binding interactions of PD-1 and PD-L1 have been studied by surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC) over the past few years, but these investigations resulted in controversy regarding the values of the dissociation constant (Kd) (Freeman et al., 2000). MST is a powerful new method for the ...

[Abstract] Until recently, whole-proteome microarrays for comprehensive studies of protein interactions were mostly produced by individual cloning and cellular expression of very many open reading frames, followed by protein isolation and purification as well as array production. To overcome this cumbersome process, we have developed a method to generate ...
Adoptive Transfer of Monocytes Sorted from Bone Marrow
[Abstract] Inflammatory Ly6Chi monocytes can give rise to distinct mononuclear myeloid cells in the tumor microenvironment, such as monocytic myeloid-derived suppressor cells (Mo-MDSC), immature macrophages, M2-like tumor-associated macrophages (TAMs), M1-like TAMs or monocyte-derived dendritic cells (Mo-DCs). This protocol describes a method to ...
In-vivo gp100-specific Cytotoxic CD8+ T Cell Killing Assay
[Abstract] Cytotoxic CD8+ T lymphocytes (CTLs) represent a crucial component of the adaptive immune system and play a prominent role in the anti-tumor immune responses of both mice and humans.
Cytotoxic CD8+ T cells are responsible for the lysis of cells expressing peptides associated with MHC class I molecules and derived ...

[Abstract] Glioblastoma (GBM) is the most common primary brain cancer in adults and has a poor prognosis. It is characterized by a high degree of cellular infiltration that leads to tumor recurrence, atypical hyperplasia, necrosis, and angiogenesis. Despite aggressive treatment modalities, current therapies are ineffective for GBM. Mouse GBM models not only ...
