Determination of permissive and restraining cancer-associated fibroblast (DeCAF) subtypes (Section 36) - Mar 5, 2024 - Abstract #AACR2024AACR_7555; P1 Analysis of a phase Ib trial FOLFIRINOX in combination with a CCR2 inhibitor (PF-04136309; NCT01413022) , we found that in patients with classical tumors, increasing permCAF probability was associated with response (r = -0.688, p<0.001)...DeCAF subtypes are associated with histological subtype in MESO (p = 0.021) and grade in KIRC (p = 0.056). Taken together, DeCAF subtypes explain the role of CAF subtypes in patients, provide a foundation for the translation of preclinical studies, and facilitate the design of future therapeutic approaches and clinical trials.

Preclinical, Journal: Chemokine CCL2 promotes cardiac regeneration and repair in myocardial infarction mice via activation of the JNK/STAT3 axis. (Pubmed Central) - Dec 12, 2023 We demonstrated in NRVMs that the CCL2 stimulated cardiomyocyte proliferation through STAT3 signaling: treatment with rCCL2 (100?ng/mL) significantly increased the phosphorylation levels of STAT3, whereas a STAT3 phosphorylation inhibitor Stattic (30??M) suppressed rCCL2-induced cardiomyocyte proliferation. In conclusion, this study suggests that CCL2 promotes cardiac regeneration via activation of STAT3 signaling, underscoring its potential as a therapeutic agent for managing MI and associated heart failure.

Bioinformatics and computer modeling-guided polymeric formulation for overcoming pancreatic cancer immune resistance (S103d (McCormick Place Convention Center)) - Aug 9, 2022 - Abstract #ACSFall2022ACS_Fall_5710; Through the combination of computer modeling and experimental screening, we developed a dual delivery modality by incorporating a CCR2 (the receptor shared by both CCL2 and CCL7) antagonist PF-6309 (PF) into the polymeric carrier system...Our work has shed light to the multi-faceted role of STING activation and provided a novel immunotherapy regimen to maximize the benefit of STING activation for PDAC treatment. In addition, this work paved a new way for bioinformatics and computer modeling-guided rational design of nanomedicine.

HYPERGLYCEMIA SENSITIZES PANCREATIC CANCER TO MACROPHAGE-SPECIFIC IMMUNOTHERAPIES: AN UPDATE (Bayview Ballroom) - May 10, 2022 - Abstract #APCM2022APCM_91; Hyperglycemia appears to sensitize PC to an otherwise ineffective CSF1R inhibitor. We are currently testing the efficacy of D30 and pexidartinib in a model of hepatic metastases and studying effectiveness of D30 combined with PF-4136309, a CCR2 inhibitor.

Review, Journal: Tumor-associated macrophages: A promising target for a cancer immunotherapeutic strategy. (Pubmed Central) - Sep 3, 2021 To date, TAM-targeted therapeutic strategies have mainly been divided into two kinds: inhibiting pro-tumor TAMs and activating anti-tumor TAMs. We reviewed the heterogeneous and plastic characteristics of macrophages in the TME and the feasible strategies to target TAMs in cancer immunotherapy and summarized the complementary effect of TAM-targeted therapy with traditional treatments or other immunotherapies.
