CD47 blockade improves the therapeutic effect of osimertinib in non-small cell lung cancer / 医学前沿

The third-generation epidermal growth factor receptor (EGFR) inhibitor osimertinib (OSI) has been approved as the first-line treatment for EGFR-mutant non-small cell lung cancer (NSCLC). This study aims to explore a rational combination strategy for enhancing the OSI efficacy. In this study, OSI induced higher CD47 expression, an important anti-phagocytic immune checkpoint, via the NF-κB pathway in EGFR-mutant NSCLC HCC827 and NCI-H1975 cells. The combination treatment of OSI and the anti-CD47 antibody exhibited dramatically increasing phagocytosis in HCC827 and NCI-H1975 cells, which highly relied on the antibody-dependent cellular phagocytosis effect. Consistently, the enhanced phagocytosis index from combination treatment was reversed in CD47 knockout HCC827 cells. Meanwhile, combining the anti-CD47 antibody significantly augmented the anticancer effect of OSI in HCC827 xenograft mice model. Notably, OSI induced the surface exposure of "eat me" signal calreticulin and reduced the expression of immune-inhibitory receptor PD-L1 in cancer cells, which might contribute to the increased phagocytosis on cancer cells pretreated with OSI. In summary, these findings suggest the multidimensional regulation by OSI and encourage the further exploration of combining anti-CD47 antibody with OSI as a new strategy to enhance the anticancer efficacy in EGFR-mutant NSCLC with CD47 activation induced by OSI.

Building on the backbone of CD47-based therapy in cancer: Combination strategies, mechanisms, and future perspectives

Described as a "don't eat me" signal, CD47 becomes a vital immune checkpoint in cancer. Its interaction with signal regulatory protein alpha (SIRPα) prevents macrophage phagocytosis. In recent years, a growing body of evidences have unveiled that CD47-based combination therapy exhibits a superior anti-cancer effect. Latest clinical trials about CD47 have adopted the regimen of collaborating with other therapies or developing CD47-directed bispecific antibodies, indicating the combination strategy as a general trend of the future. In this review, clinical and preclinical cases about the current combination strategies targeting CD47 are collected, their underlying mechanisms of action are discussed, and ideas from future perspectives are shared.

Pretreatments with hypertonic solution and cobalt chloride in bone marrow mesenchymal stem cell transplantation for treatment of degenerative disc disease / 中国组织工程研究

BACKGROUND:Stem cel therapy has been used for prevention and treatment of degenerative disc disease. Considering the special microenvironment in the intervertebral disc, the survival rate and differentiation ability of transplanted cels are decreased, which may lead to the poor efficacy of stem cel therapy. How to improve the survival ability and therapeutic effect of the transplanted cels is the focus of stem cel therapy for degenerative disc disease. OBJECTIVE: To investigate the effects of cobalt chloride combined with hypertonic solution pretreatment on bone marrow mesenchymal stem cels that wil be transplanted for treatment of degenerative disc disease. METHODS:(1)In vitro cel experiment: bone marrow mesenchymal stem cels were divided into three groups and subjected to normal culture medium (normal control group), 1% hypertonic mother solution (hypertonic group), 100 μmol/L cobalt chloride (hypoxia group), or 1% hypertonic mother solution plus 100 μmol/L cobalt chloride (combined group) for 1 week. Then, 2% hypertonic solution and 200 μmol/L cobalt chloride cobalt chloride were used to simulate the anaerobic and hypertonic environment intervenes in pretreated and untreated bone marrow mesenchymal stem cels for 24 hours. After that, RT-PCR was used to detect the expression of caspase-3 for apoptosis evaluation. (2)In vivo animal experiment: Sprague-Dawley rats were divided into model, cel transplantation and hypertonic plus hypoxic groups. Rat models of intervertebral disc degeneration were made in these three groups. After modeling, rats in these three groups were given no treatment, bone marrow mesenchymal stem cel transplantation or transplantation of bone marrow mesenchymal stem cels which were subjected to hypertonic and hypoxia pretreatments into the intervertebral disc. Two weeks later, immunohistochemistry and RT-PCR methods were used to detect cel distribution and related gene expression, respectively, thereby to evaluate the therapeutic effect of stem cels. RESULTS AND CONCLUSION: (1)In vitro cel experiment: caspase-3 mRNA expression was significantly reduced in pretreated bone marrow mesenchymal stem cels compared with the untreated cels (P < 0.05). (2)In vivo animal experiment: compared with the control group, the caspase-3 and interleukin-1β in the intervertebral disc and a number of degenerative indexes were decreased in the cel transplantation. Compared with the cel transplantation group, these indicators had better outcomes in the hypertonic plus hypoxic group (P < 0.05). These findings indicate that bone marrow mesenchymal stem cels have therapeutic potential for degenerative disc disease, and have better adaptability and transplantation effects by hypertonic and hypoxia pretreatments.

Virological impact of stalk region of neuraminidase in influenza A/Anhui/1/05 (H5N1) and A/Ohio/07/2009 (H1N1) viruses / 病毒学报

This study aims to investigate the virological impact of the stalk region and cysteine (C) in neuraminidase (NA) of influenza A/Anhui/1/05 (H5N1) and A/Ohio/07/2009 (H1N1) viruses. The NA of A/ Anhui/1/05 (H5N1), defined as AH N1, lacked 20 amino acids (including C, defined as s20) as compared with NA of A/Ohio/07/2009 (H1N1) (defined as 09N1). We deleted s20 of 09N1 to construct 09N1-s20, and inserted s20 into AH N1 to construct AH N1+s20. To investigate the impact of C on the biological function of NA, we deleted C in 09N1 to construct 09N1-C and inserted C into AH N1 to construct AH N1-C. The pseudo-type viral particle (pp) system was used to evaluate the impact of these mutants on virology. The combination of 09N1-C and 09H1 (defined as 09H1::09N1-C) showed an infectivity 8 times that of the wild type 09H1::09N1, while the infectivity of the combination of AH N1+C and AH H5 (defined as AH H5::AH N1+C) was much lower than that of the wild type AH H5::AH N1. The infectivity of the combination of 09N1-s20 and 09H1 (defined as 09H1::09N1-s20) was 4 times that of the wild type 09H1::09N1; the infectivity of the combination of AH N1+s20 and AH H5 (defined as AH H5:: AH N1+s20) was 1/7 that of the wild type AH H5::AH N1. The co-existence of 09N1-C and AH H5 displayed 6 times the infectivity of AH H5::09N1, while the infectivity of 09H1::AH N1+C was very low. Multimer analysis showed that in the wild type 09N1, the forms of NA were dimer > tetramer > monomer; the major component of NA in 09N1-C was monomer; in 09N1-s20, the forms of NA were monomer > dimer. AH N1 was mainly composed of monomer; in AH N1+s20, the forms of NA were dimer > monomer > tetramer; in AH N1+C, the forms of NA were dimer > tetramer. Deletion of C or s20 from 09N1 did not change the expression of NA. The study suggested that deletion of C from the stalk region of NA in A/Ohio/07/2009 (H1N1) increases infectivity. Insertion of C into NA's stalk region of A/ Anhui/1/05 (H5N1) significantly decreases infectivity. Cysteine deletion in the stalk region is important for the infectivity of A/Anhui/1/05 (H5N1) and A/Ohio/07/2009 (H1N1). It may interfere with the infectivity via changes in NA polymerization.
