There are numerous macrophages and dendritic cells in lymph nodes (LNs). Recent studies have highlighted that sinus (SMs) LNs possess antigen-presenting capabilities related to anti-cancer immune responses. In this study, we assessed the distribution of SMs mesenteric removed during surgery for colorectal cancer. A marked reduction was noted elderly patients, particularly those over 80 years old. We observed a disappearance CD169-positive where were reduced. silico analysis publicly...
The tumor suppressor TP53 gene, the most frequently mutated gene in human cancers, produces product protein p53, which plays an essential role DNA damage. p53 mutations may contribute to tumorigenesis by loss of suppressive functions and malignancy cancer cells via gain-of-oncogenic functions. We previously reported that mutant proteins form aggregates cytoplasmic were associated with poor prognosis ovarian cancer. However, prognostic impact aggregation other tumors including lung squamous...
Abstract Recent advances in anti-cancer therapy have indicated the significance of tumour immune microenvironment progression and resistance to therapy. This study investigated primary colorectal cancer (CRC) tissues resected from 180 cases a single institute region highly endemic for human T-cell leukaemia virus type 1 (HTLV-1) carriers. Among those cases, 35 HTLV-1 carriers were identified. CRC patients who significantly older (mean age: 76.9 vs. 72.7 years, P = 0.0341), with lower...
Managing immune-related adverse events (irAEs) caused by cancer immunotherapy is essential for developing effective and safer therapies.
