The fatty acid receptor CD36 promotes macrophage infiltration via p110γ signaling to stimulate metastasis.

Introduction: Metabolic regulators are key in controlling immune cell fate in the tumor microenvironment. The accumulation of tumor-associated macrophages (TAMs) in cancer greatly contributes to metastasis and poor outcome. However, the metabolic pathways responsible for TAM accumulation are largely unknown.

Systemic loss of CD36 aggravates NAFLD-related HCC through MEK1/2-ERK1/2 signaling pathway.

Background & Aims: CD36, a membrane protein widely present in various tissues, is crucial role in regulating energy metabolism. The rise of HCC as a notable outcome of NAFLD is becoming more apparent. Patients with hereditary CD36 deficiency are at increased risk of NAFLD.

Circulating soluble CD36 as a novel biomarker for progression and prognosis of HBV-related liver diseases.

Background: Our previous study suggested CD36 may be a positive regulator of hepatitis B virus (HBV) replication . Therefore, the present study aimed to investigate whether circulating soluble CD36 (sCD36) could serve as a diagnostic and prognostic biomarker for HBV-related liver diseases based on the clinic collected data.

Methods: A total of 282 subjects were divided into healthy controls (HC,  = 47), chronic hepatitis B (CHB,  = 68), HBV-related liver cirrhosis (HBV-LC,  = 167).

HIF-2α-induced upregulation of CD36 promotes the development of ccRCC.

Clear cell renal cell carcinoma (ccRCC) is characterized by the abundance of lipid droplets and the activation of the hypoxia-inducible factor (HIF) signaling pathway. However, the lipid reprogramming induced by HIF signaling in ccRCC is not fully understood. In this study, we found that the fatty acid receptor CD36 was highly expressed in human ccRCC tissues and ccRCC cell lines.

CD36-mediated metabolic crosstalk between tumor cells and macrophages affects liver metastasis.

Liver metastasis is highly aggressive and treatment-refractory, partly due to macrophage-mediated immune suppression. Understanding the mechanisms leading to functional reprogramming of macrophages in the tumor microenvironment (TME) will benefit cancer immunotherapy. Herein, we find that the scavenger receptor CD36 is upregulated in metastasis-associated macrophages (MAMs) and deletion of CD36 in MAMs attenuates liver metastasis in mice.

CD36 promotes de novo lipogenesis in hepatocytes through INSIG2-dependent SREBP1 processing.

Objective: Enhanced de novo lipogenesis (DNL) in hepatocytes is a major contributor to nonalcoholic fatty liver disease (NAFLD). Fatty acid translocase (FAT/CD36) is involved in the pathogenesis of NAFLD through facilitating free fatty acids uptake. Here, we explored the effects of CD36 on DNL and elucidated the underlying mechanisms.
