Mutant proteins, high potency inhibitory antibodies and fimch crystal structure

The present invention provides bacterial immunogenic agents for administration to humans and non-human animals to stimulate an immune response. It particularly relates to the vaccination of mammalian species, especially human patients, with variants of the E. coli FimCH protein that elicit antibodies that have better functional inhibitory activity than antibodies raised against wild type protein. In particular, such variants include mutations that promote a more open confirmation of the FimH protein, particularly in regions involved in mannose binding, to expose regions previously poorly exposed and mutations that abolish a significantly reduce mannose binding. In another aspect, the invention provides antibodies against such proteins and protein complexes that may be used in passive immunization to protect or treat pathogenic bacterial infections. The present invention also provides machine readable media embedded with the three-dimensional atomic structure coordinates of FimCH bound to mannose, and subsets thereof, and methods of using the crystal structure to provide candidate amino acid residues for mutation.

Application of MBL in preparing drug for preventing or treating obesity and method for screening drug for preventing or treating obesity

The invention relates to application of MBL in preparing a drug for preventing or treating obesity and a method for screening the drug for preventing or treating the obesity, and belongs to the technical field of biotechnology and medicine. The MBL levels of normal control serum and obese patient serum are studied, and the MBL level of the obese patient serum is obviously less than the normal control serum. The gene editing technology is utilized to obtain mannose-binding lectin gene-deficient mice and find that MBL gene knockout significantly aggravates the blood glucose metabolism disorder in obese mice, and the fat cell volume is increased. An experiment of MBL inhibiting adipocyte differentiation shows that MBL can inhibit the adipocyte differentiation by down regulating the adipogenicdifferentiation related genes C / EBP alpha and PPAR gamma. From above, the MBL and the obesity have a close relationship. Therefore, the mannose-binding lectin can be used for preparing the drug for preventing or treating the obesity and preparing the drug for inhibiting the adipogenic differentiation of 3T3-L1 preadipocytes.
