1.TREM-2 and tumors
Journal of International Oncology 2021;48(2):101-104
Triggering receptors expressed on myeloid cells-2 (TREM-2) is a newly discovered immunoglobulin receptor, which plays an important role in inflammation and immunoreaction. Several recent studies have shown that TREM-2 is aberrantly expressed in various types of cancers such as lung cancer, gastric cancer, liver cancer, colorectal cancer, renal carcinoma and glioma, and it is widely participated in regulating malignant tumor initiation, progression, invasion and metastasis through different signal pathways. TREM-2 is expected to provide evidence for the diagnosis and treatment of malignant tumors.

The Haemophilus influenzae (Hi) is a common opportunistic pathogen from human respiratory tract. The lower immunity can cause the disease. After the biofilm (BF) is formatted by Hi at the site of infection, the antibiotic sensitivity is declined, which often causes the chronic disease, inducing the difficulty in clinical treatment. In recent years, the pathogenic?ity of Hi BF and BF form related factors have gradually become the focus of clinical and basic research. This paper reviewed recent studies as following.
