    Abstract: The present invention relates to a composite membrane (10) comprising a fibrous fabric (1) of nanofibres (11), wherein the thickness of the fabric (1) is between 10 nm and 50 μm and said fabric is impregnated with a wetting liquid (A). According to the invention, the composite membrane is immersed in a second fluid (B) which is immiscible with the wetting liquid (A), forming an A/B interface between the wetting liquid (A) and the immiscible fluid (B), and the composite membrane is capable of remaining tensioned when it is compressed from its resting state until reaching dimensions corresponding to 5% of its dimensions in the resting state, and when it is stretched from its compressed state until reaching dimensions corresponding to 2000% of the length in the compressed state. The present invention also relates to a process for manufacturing such a membrane.

    Abstract: The invention is in the field of therapy of antibody deficiencies. Inventors demonstrate for the first time in both controls and IgA-deficient patients. systemic anti-microbiota IgG responses correlate with reduced inflammation suggesting that systemic IgG responses contribute to the gut microbiota confinement. Furthermore. SIgAd-associated inflammation is inversely correlated with systemic anti-commensal IgG responses, which may thus serve as a second line of defense. Altogether, these data suggest that systemic IgG and intestinal IgA cooperate in different body compartments to limit systemic pro-inflammatory pathways. As selective IgA deficient patients harbour elevated seric anti-commensal IgG levels. these findings suggest that in selective IgA deficiency, microbiota confinement is obtained at the price of a strong inflammatory response. Accordingly. the invention relates to a composition containing immunoglobulins A (IgA). more particularly secretory IgA. for use by oral administration in the prevention or treatment of antibody deficiencies such as SIgAd (Selective IgA deficiency) or common variable immunodeficiency (CVID) and associated inflammatory diseases.
