The invention relates to an in vitro method for identifying microRNAs or the target mRNAs thereof, the expression of which during the infection of cells by a virus using a cell receptor and at least one cell co-receptor for entering the cell, is specifically modified on the basis of the cell co-receptor used by the virus for its entering the cells, comprising: i) determining the microRNA expression levels in a test cell expressing a receptor, a first co-receptor and at least one other co-receptor, after infection by a first virus using the first co-receptor and by at least one other virus using another co-receptor, respectively; ii) identifying the microRNAs, the expression level of which is modulated during the infection by each of the viruses in relation to the expression level in the uninfected cells; iii) comparing the thus-identified microRNAs; iv) selecting the microRNAs, the modification of the expression level of which is specific to the use of a co-receptor; v) optionally identifying the target mRNAs of the thus-selected microRNAs.

The invention relates to a method for preparing a synthetic talc composition. According to said method, a kerolite composition is subjected to an anhydrous thermal treatment carried out at a pressure lower than 5 bar, from over a few hours up to over a few days, at a treatment temperature higher than 300° C. The invention also relates to a synthetic talc composition prepared in this way, the synthetic talc particles of the composition being exclusively of chemical formula —(Si4)Mg3O10(OH)2— and identifiable, during X-ray diffraction, by the presence of a characteristic diffraction peak located at a distance of between 9.40-9.68 and corresponding to a plane (001). Said synthetic talc particles also have a thermally stable crystalline structure of stacked laminae, which is very similar to that of a natural talc and has a particle size smaller than approximately ten micrometers.
