Q&A: Biologic drugs are reinvented to treat infectious diseases
Lumen scientists were the first to crack that long-standing barrier. Once that was done, we started looking around for useful applications. To our surprise, we discovered that there is actually a very robust literature on orally delivered therapeutic proteins, although most people are unaware of it.
Therapeutic interventions for gut dysbiosis and related disorders in the elderly: antibiotics, probiotics or faecal microbiota transplantation? - PubMed
Ageing and physiological functions of the human body are inversely proportional to each other. The gut microbiota and host immune system co-evolve from infants to the elderly. Ageing is accompanied by a decline in gut microbial diversity, immunity and metabolism, which increases susceptibility to in …
Link between gut microbiota dysbiosis and childhood asthma: Insights from a systematic review - PubMed
Asthma, a chronic inflammatory disorder of the airways, is a prevalent childhood chronic disease with a substantial global health burden.

Clostridium septicum manifests a bile salt germinant response mediated by Clostridioides difficile csp gene orthologs - PubMed
Clostridium septicum infections are highly predictive of certain malignancies in human patients. To initiate infections, C. septicum spores must first germinate and regain vegetative growth. Yet, what triggers the germination of C. septicum spores is still unknown. Here, we observe that C. septicum …
