Macrophage Mtdh deficiency discordantly regulated tumor growth and metastasis through increased thrombospondin-1 production

Objective
Metadherin (MTDH) is a recognized oncogene involved in the progression and metastasis of various cancers. However, further studies are needed to elucidate the biological role of MTDH, which is expressed in macrophages during tumor progressio…

Modulating the tumor immune phenotypes by radiotherapy: formulating and validating the combination therapy of radiation, PD-L1, and TIM-3 blockade in colorectal cancer

Background
Most colorectal cancers (CRCs) are mismatch repair-proficient (pMMR) and microsatellite stable (MSS), and they respond poorly to immune checkpoint inhibitors (ICIs). Radiotherapy (RT) can promote antitumor immunity but may also trigger adap…

Specific depletion of TIGIThigh CD226- clonally expanded intratumoral Tregs defines safe and effective TIGIT targeting

Background
Global clinical programs based on TIGIT (T cell immunoglobulin and ITIM domain) blockade have been terminated due to inadequate clinical efficacy. New approaches are needed to increase the antitumor activity of anti-TIGIT-based immunotherap…

HOXD13-mediated immune crosstalk between cancer cells and tumor-associated macrophages drives colorectal cancer progression

Background
The complex tumor microenvironment (TME) of colorectal cancer (CRC), composed of diverse cellular components and dynamic interactions, constitutes a major barrier to effective immunotherapy and facilitates disease progression. There is a pr…

Partitioned overall survival: comprehensive analysis of survival states over 4 years in CheckMate 9ER comparing first-line nivolumab plus cabozantinib versus sunitinib in advanced renal cell carcinoma

Background
Immune checkpoint inhibitor (ICI)-based regimens can be associated with prolonged survival and disease control after treatment discontinuation without further anticancer therapy. An integrated, comprehensive partitioned survival analysis de…

Targeting PKMYT1 enhances antitumor immune responses to PD-L1 blockade in castration-resistant prostate cancer

Background
Although immunotherapy has revolutionized cancer treatment, its efficacy in castration-resistant prostate cancer (CRPC) remains limited, largely due to an immunologically “cold” tumor microenvironment with scarce T-cell infiltration. Unrave…

Preventing surgery-induced natural killer cell suppression and metastases by inhibiting PI3K-gamma signaling in myeloid-derived suppressor cells

Background
Myeloid-derived suppressor cells (MDSCs) have a dominating presence in the postoperative period, mediating the suppression of natural killer (NK) cells and promoting cancer metastases after surgery. However, their phenotype and effects on p…

Targeting AKR1B1 reprograms tumor-associated macrophages to enhance antitumor immunity

Background
Tumor-associated macrophages (TAMs) are key drivers of the immunosuppressive tumor microenvironment (TME), thereby limiting the efficacy of immune checkpoint inhibitors (ICIs). However, the underlying mechanisms remain unclear.

Methods
Bot…

Tumor neoantigen gene C7orf50 remodels the immune microenvironment by recruiting tumor-associated macrophages to promote hepatocellular carcinoma progression and lung metastasis

Background
Hepatocellular carcinoma (HCC) is a global health challenge with high mortality rates, particularly in patients with advanced disease and lung metastasis. T-cell receptor (TCR)-T cell therapy based on specific neoantigens, is an emerging tr…
