T cell-redirecting antibody for treatment of solid tumors via targeting mesothelin.

T cell engaging bispecific antibodies (TCBs) have recently become significant in cancer treatment. In this study we developed MSLN490, a novel TCB designed to target mesothelin (MSLN), a glycosylphosphatidylinositol (GPI)-linked glycoprotein highly expressed in various cancers, and evaluated its efficacy against solid tumors. CDR walking and phage display techniques were used to improve affinity of the parental antibody M912, resulting in a pool of antibodies with different affinities to MSLN.

A novel bispecific antibody drug conjugate targeting HER2 and HER3 with potent therapeutic efficacy against breast cancer.

Antibody drug conjugate (ADC) therapy has become one of the most promising approaches in cancer immunotherapy. Bispecific targeting could enhance the efficacy and safety of ADC by improving its specificity, affinity and internalization. In this study we constructed a HER2/HER3-targeting bispecific ADC (BsADC) and characterized its physiochemical properties, target specificity and internalization in vitro, and assessed its anti-tumor activities in breast cancer cell lines and in animal models.

Long-term passaging of pseudo-typed SARS-CoV-2 reveals the breadth of monoclonal and bispecific antibody cocktails.

The continuous emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants poses challenges to the effectiveness of neutralizing antibodies. Rational design of antibody cocktails is a realizable approach addressing viral immune evasion. However, evaluating the breadth of antibody cocktails is essential for understanding the development potential.

Paclitaxel-etoposide-carboplatin/cisplatin versus etoposide-carboplatin/cisplatin as first-line treatment for combined small-cell lung cancer: a retrospective analysis of 62 cases.

Objective: To compare the efficacy and adverse effects of paclitaxel-etoposide-carboplatin/cisplatin (TEP/TCE) regimen with those of etoposide-carboplatin/cisplatin (EP/CE) regimen as first-line treatment for combined small-cell lung cancer (CSCLC).

Methods: A retrospective study was conducted on 62 CSCLC patients who were treated at Tianjin Medical University Cancer Institute and Hospital from July 2000 to April 2013 and administered with TEP/TCE regimen (n=19) or EP/CE regimen (n=43) as first-line CSCLC treatment. All patients received more than two cycles of chemotherapy, and the response was evaluated every two cycles.

[Polymorphism of fifteen short tandem repeat loci in Tibetan of Changdu area].

Objective: To investigate the genetic polymorphism of 15 autosomal short tandem repeat (STR) loci, i.e. D5S818, FGA, D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX and D18S51, in Tibetan population of Changdu area, and to analyze the genetic relationship between this population and other Asian populations.
