Orally delivered microbial exosomes induce anti-tumor immunity

Orally delivered microbial exosomes induce anti-tumor immunity

The therapeutic effects of transplanted stem cells can be mediated by their exosomes. Since exosomes offer relative simplicity and are tolerated without the need for immunosuppressive drugs, there is increasing interest in using exosomes for therapy rather than cells. There may be advantages to using exosomes from microorganisms therapeutically too.

Does too little phagocytosis lead to autism?

Does too little phagocytosis lead to autism?

Tissue remodeling and homeostasis are the processes that modulate and maintain the size and shape of tissues. Phagocytosis plays an important role in these processes. A recent publication in PNAS provides evidence that a mutation that reduces the efficiency of phagocytosis may lead to abnormalities in brain development that are associated with enlarged brains seen in some instances of autism.

Register for our exosome webinar on July 1st

Dr Shu will be discussing his recent review paper "Co-Isolation of Cytokines and Exosomes: Implications for Immunomodulation Studies". Exosomes play a vital role in intercellular communication and their immunomodulatory potential has become an important focus in cancer research. In melanoma, tumor-derived exosomes drive immunosuppression within the tumor microenvironment. In this webinar, Dr Shu examines the possibility that free cytokines in 'purified' exosome samples may be causing biological effects that can be wrongly attributed to exosomes.
