Abstract

A method for the expression of a protein of interest by a bacterium, notable in that it comprises the culturing of a bacterium temporarily or continuously expressing an Hsp protein, in that said bacterium also comprises a nucleic acid sequence, encoding a protein of interest, under the control of a lac promoter and in that said bacterium is cultured in a medium which does not contain IPTG or a metabolized molecule in such a way as to automatically induce the induction of transcription from the lac promoter.

Abstract

The present invention relates in particular to a method for the expression of a protein of interest by a bacterium, notable in that it comprises the culturing of a bacterium temporarily or continuously expressing an Hsp protein, in that said bacterium also comprises a nucleic acid sequence, encoding a protein of interest, under the control of a lac promoter and in that said bacterium is cultured in a medium which does not contain IPTG or a metabolized molecule in such a way as to automatically induce the induction of transcription from the lac promoter.

Abstract

The present invention relates to a method for predicting the risk of acquiring an age-related low-grade inflammation for a subject, said method comprising a) providing a biological sample from a subject, b) determining in said sample the level of at least one biomarker selected from the group consisting of a compound of molecular weight between 859-863 g/mol and which is an alkylacylphosphatidylcholine, a compound of molecular weight between 861-86 g/mol and which is a diacylphosphatidylcholine, a compound of molecular weight between 791-794 g/mol and which is an alkylacylphosphatidylcholine, a compound of molecular weight between 522-525 g/mol and which is a monoacylphosphatidylcholine, octadecanoylcarnitine (C18), and tryptophan, c) comparing the level of the at least one biomarker to a reference level, and d) determining whether said subject is likely to be at risk of acquiring an age-related low-grade inflammation, when the level of biomarker(s) deviate significantly from the respective reference level.

Abstract

The present invention relates to the field of nutrition; in particular to the prevention and/or treatment of malnutrition. One embodiment of the present invention relates to a nutritional composition enriched in cysteine for use in the treatment and/or prevention of malnutrition and disorders related thereto. Such a composition may in particular, but not exclusively, be useful for the elderly population.
