The present disclosure provides a class of specific anti-PD-L1 single-domain antibodies that block PD-L1/PD-1 interaction, and humanized antibodies, fusion proteins, and pharmaceutical compositions prepared based on the single-domain antibodies, and use thereof.

The present disclosure provides a class of specific anti-PD-L1 single-domain antibodies that block PD-L1/PD-1 interaction, and humanized antibodies, fusion proteins, and pharmaceutical compositions prepared based on the single-domain antibodies, and use thereof.

The disclosure provides skin probiotics, fermented media extract and fermentation byproducts thereof for the treatment of skin disease and disorders as well as for the prevention/treatment of acne and MRSA.

The invention provides antibodies, antigen binding fragments thereof, chimeric antigen receptors (CARs), and engineered T cell receptors, polynucleotides encoding the same, and in vitro cells comprising the same. The polynucleotides, polypeptides, and in vitro cells described herein can be used in an engineered CAR T cell therapy for the treatment of a patient suffering from a cancer. In one embodiment, the polynucleotides, polypeptides, and in vitro cells described herein can be used for the treatment of multiple myeloma.

The present invention discloses a compound of anilino polyethylene glycol ether cycloquinazoline substituted with a substituted arylmethyl heteroatomic group having the structure of formula (I) below, or a pharmaceutically acceptable salt, ester or solvate thereof, and a pharmaceutical composition comprising the same. The compound and pharmaceutical composition disclosed herein can be used in tumor targeted therapy and in the regulation of tumors and related diseases. ##STR00001##

A method for treating autoimmune and/or inflammatory disease includes a step of identifying a subject exhibiting symptoms of autoimmune and/or inflammatory disease administering a fasting mimicking diet. A probiotic composition for gastrointestinal autoimmune and/or inflammatory disease Bacteroides acidifaciens, Bifidobacterium choerinum, and combinations thereof is also provided.

The present invention discloses application of a bile acid composite bacterial agent in the preparation of feed additives for mutton sheep. The bile acid composite bacterial agent comprises Parabacteroides distasonis bacterial suspension and bile acid, and the Parabacteroides distasonis bacterial suspension is obtained by cultivation and fermentation of Parabacteroides distasonis LCG-06 with the deposit number CGMCC No. 20820. The bile acid composite bacterial agent of the present invention has natural components and has no toxic and side effects, and can significantly increase the growth rate of mutton sheep and promote nutrition absorption, accelerate the decomposition of in vivo fat of mutton sheep, thereby reducing the body fat percentage of mutton sheep, increasing the slaughter weight and slaughter rate of mutton sheep, increasing the incomes for breeding of mutton sheep. Therefore, it has broad application prospects.

The invention relates to novel heterocyclic compounds and pharmaceutical preparations thereof. The invention further relates to methods of treating or preventing cancer using the novel heterocyclic compounds of the invention.
