The present invention relates to pharmaceutical and cosmetic compositions comprising at least one agonist ligand, which is specific for receptors of the RAR-&ggr; type, which are characterized as inducers of apoptosis in at least one cell population in which apoptosis can be induced by activating receptors of the RAR-&ggr; type. In one aspect of the present invention, there is provided a method of combating photoinduced or chronological ageing of skin, said method comprising administering an effective amount of at least one agonist ligand which is specific for receptors of the RAR-&ggr; type to combat photoinduced or chronological aging of skin, wherein the agonist ligand has a ratio R which is equal to or greater than 10.

Use of a RAR-&ggr;-specific agonist ligand for increasing the rate of apoptosis

The use of at least one &ggr;-RAR receptor-specific agonist ligand to prepare a pharmaceutical composition for increasing the rate of apoptosis in at least one cell population in which apoptosis may be induced by activating &ggr;-RAR receptors is disclosed. The composition is particularly useful for treating a disease or disorder related to an insufficient rate of apoptosis in at least one cell population in which apoptosis may be induced by activating &ggr;-RAR receptors. The use of at least one &ggr;-RAR receptor-specific agonist ligand as the apoptosis inducer in a cosmetic composition is also disclosed. Said composition may be used to prevent and/or control photo-ageing or chronological ageing of the skin.

Methods of cosmetically or therapeutically treating diseases or disorders in cell populations whose pathology is linked to an inadequate rate of apoptosis by administering a therapeutically effective amount of 6-3-(1-adamantyl)-4-hydroxyphenyl)-2-naphthanoic acid.

The differentiation of preadipocytic cells into adipocytic cells, in particular for correcting insulin-resistance disease states in mammalian organisms, notably in humans, for example type II diabetes and cardiovascular disorders such as hypertension and atherosclerosis, is stimulated by treating such preadipocytic cells, or a patient in need of such treatment, with an effective amount of (a) at least one ligand displaying affinity for the nuclear receptors for retinoic acid and/or isomers thereof, preferably at least one ligand displaying a specific affinity for the RAR receptors and even more preferably the RAR-&agr; receptor and (b) at least one fatty acid, e.g., a polyunsaturated fatty acid.

The subject invention relates to a method of diagnosing epidermis differentiation disorders in a patient by obtaining an epidermis sample from the patient, adding to the sample, antibodies that specifically bind to an antigen of the stratum corneum, the said antigen being specifically recognized by BC 21 monoclonal antibody and detecting the presence or absence of the antibodies that are specifically bound to the epidermis sample.

Method of diagnosing epidermis differentiation disorders in a patient

The subject invention relates to monoclonal antibodies which react with antigenic determinants which are present of the stratus corneum of human epidermis. Furthermore, the invention also relates to methods of using such monoclonal antibodies in immunoassays. One monoclonal antibody of the present invention which is particularly useful is BC 21.
