In vivo syngeneic tumor models for novel drug assessment and MoA deciphering in a cost-saving way

10 / 09 / 2019

How about an opportunity to assess your compounds in a comprehensive and cost-effective manner?

Involvement of CD8 T cells in the tumor growth control and in the response to PD1 and PDL1 antibodies

09 / 12 / 2019

Immunotherapy-based anti-cancer strategies such as immune checkpoint inhibitors promote antitumor immune response driven by the mobilization of effector immune cell activity and/or reversal of immunosuppressive mechanisms.

In vitro assessment of functional response to PD1 blockade

06 / 27 / 2019

Relying on our validated in vitro immune cell activation assay based on the HTRF quantitation of key cytokine release, we recently documented functional characterization of PD1 blockade.

Combination of in vivo monitoring and flow cytometry-based immunoprofiling on syngeneic tumor models

05 / 24 / 2019

Syngeneic tumor models were becoming invaluable for preclinical development and evaluation of immuno-based therapies in the presence of a functional immunocompetent system. Explicyte is providing a series of syngeneic mouse models including subcutaneous and orthotopic models, which were fully characterized in terms of their responsiveness to immune checkpoint inhibitors (ICI) and their immune infiltration features using a high throughput-compatible flow cytometry platform.

Shuttle session: M2 Macrophage Suppression Assay for immunotherapeutic screening

04 / 09 / 2019

We are proud to offer a first in vitro shuttle session on our newly validated M2 macrophage suppression assay, which will take place early June, 2019 – thereby providing an opportunity to timely and cost-effectively assess novel immunotherapeutics.

M2 Macrophage Suppression Assay

03 / 13 / 2019

Our newly validated M2 suppression assay based on i) the co-culture of autologous monocyte-derived M2 macrophages and activated CD4+ T cells (or PBMCs) and on ii) the quantitation of IFNg levels as surrogate of T cell activation, is specifically designed to assess new immunotherapeutics for their modulatory activity on the phenotype and function of M2 macrophages. 

Candidate compounds can thus be evaluated as single agents or in combinatorial treatments, for their potential to repolarize / switch M2 macrophages and to antagonize M2-mediated T cell suppression.

Intratumoral microdialysis-based approach to assess tumor immunometabolism & specific immunometabolic pathways-targeting

02 / 20 / 2019

Syngeneic tumor models were becoming invaluable for preclinical development and evaluation of immuno-based therapies. Nevertheless, the immunometabolic features of these tumors models, which may likely underlie responsiveness to immunotherapies, are still not well understood and become thus primordial to be defined for tumor model characterization and selection of the appropriate ones, for target validation, drug development, and assessment of the efficacy potential of drug candidates.

New shuttle session with our in vivo syngeneic subcutaneous tumor models – for cost-saving efficacy studies

01 / 17 / 2019

Explicyte is planning a new in vivo shuttle session by early March, thereby providing an opportunity to cost-effectively assess your drug candidates in our well-suited immunocompetent syngeneic subcutaneously-implanted tumor models, over studies where a significant cost part will be supported by ourselves.

Neutrophil chemotaxis assay for cancer immunotherapy screening

12 / 06 / 2018

Besides their antimicrobial functions, neutrophils are likely infiltrating many types of tumors and increasing evidence correlate the tumor-associated neutrophils (TANs) with poor clinical outcome thereby supporting their role in tumor development. Recruitment of such TANs is indeed driven by key chemokines including the prototypical CXCL8 (IL8) or CXCL1 produced by tumor cells or its microenvironment. In turns, TANs might be involved in the recruitment of other immune cell populations (eg. Tregs, TAMs, etc), all together maintaining the local immunosuppressive microenvironment. Therefore acting on neutrophil recruitment and migration represents a valuable cancer immunotherapy strategy.

Start the New Year with an in vivo shuttle session on our syngeneic orthotopic glioblastoma mouse model

11 / 14 / 2018

To get the opportunity to cost-effectively assess your drug candidates in our well-suited immunocompetent syngeneic model, do not miss our new in vivo glioblastoma shuttle session by mid-January 2019, in which a cost part will be supported by Explicyte.
