摘要:
The present disclosure relates to methods and products for reducing side effects associated with immunotherapy using immune agonist antibodies. In certain embodiments, the present disclosure provides a method of reducing one or more side effects associated with immunotherapy using an immune agonist antibody alone, or in combination with an immune checkpoint inhibitor, in a subject suffering from a cancer, the method comprising modifying the gut microbiota in the subject and thereby reducing the one or more side effects associated with the immunotherapy in the subject.

The present disclosure relates to methods for detecting functional autoantibodies and to diagnostic and prognostic applications of the methods. In certain embodiments, the present disclosure provides a method of detecting a functional autoantibody against an antigenic target, the method comprising exposing a cell expressing the antigenic target to the autoantibody, wherein the antigenic target has an activity to alter the level of reactive oxygen or nitrogen species in the cell and binding of the autoantibody to the antigenic target alters the activity of the antigenic target, and detecting the functional antibody on the basis of a change in the level of the reactive oxygen or nitrogen species in the cell.
摘要:
A method of detecting autoantibodies associated with Ro/La autoimmunity comprising detecting, in a serum sample or other sample comprising immunoglobulin G (IgG), autoantibodies to a Ro and/or La antigen comprising a variable (V)-region molecular signature comprising an unusual or common heavy (H) and light (L)-chain pairing and/or at least one mutation in one or more of said H- and L-chains and/or an adjacent region. The method enables the detection of autoantibodies associated with one or more autoimmune disease or disorder characterised by Ro/La autoimmunity such as Sjögren's syndrome (SS), systemic lupus erythematosus (SLE), neonatal lupus syndrome, other systemic rheumatic diseases, polymyositis, progressive systemic sclerosis, primary biliary cirrhosis and congenital heart block (CHB).
摘要:
A method of identifying a detectable molecular signature for an antibody or antibodies of interest (eg autoantibodies associated with one or more autoimmune diseases) wherein the molecular signature comprises an Unusual or common heavy (H)-chain and light (L)-chain pairing and/or at least one mutation in one or more of said H- and L-chains and/or an adjacent region. The detection of antibodies comprising such a molecular signature, preferably by using a targeted mass spectroscopy (MS) approach to directly sequence the antibodies or a part(s) thereof, can provide a diagnostic biomarker for one or more disease or disorder.
摘要:
The present invention relates generally to the field of tissue modification, and in particular, but not exclusively, to methods of modifying cells of ocular and particularly corneal tissue to produce immunoglobulins or immunoglobulin fragments. The invention also relates to modified ocular cells and tissues, to expression vectors utilised in such methods, to methods of xeno- and allo-transplantion using the modified tissue and to methods of therapy of ocular diseases and disorders. In a preferred embodiment of the invention there is provided a method of modifying cells of ocular tissue to produce an immunoglobulin or immunoglobulin fragment of interest, which comprises exposing ocular tissue to an effective concentration for transfection of an expression vector comprising a nucleotide sequence encoding for the immunoglobulin or immunoglobulin fragment, for a period sufficient to allow transfection, such that cells of said ocular tissue produce the immunoglobulin or immunoglobulin fragment.
摘要:
This invention relates to a method for the isolation of trophoblast (placental) cells from the blood of a pregnant mammal so as to provide the essential starting material, namely cells derived from the fetus, to enable genetic and/or biochemical information about the fetus to be obtained. In particular, this invention relates to the use of monoclonal antibodies specific for membrane protein markers on mammalian trophoblasts to isolate trophoblast cells from maternal blood. These cells may then be used to obtain fetal genetic and/or biochemical information early in pregnancy. The present invention is particularly relevant for detecting human fetal abnormalities.
摘要:
A method of enhancing embryo implantation in a subject is disclosed which comprises administering to the uterine cavity of the subject a formulation comprising copper and/or zinc in an amount effective to stimulate endometrial production of leukaemia inhibitory factor (LTF) and' or vascular endothelial growth factor ( VEGF). Alternatively, a device may be inserted into the uterine cavity of the subject, wherein the device comprises copper and/or zinc, for a period of time that is effective to stimulate endometrial production of LIF and/or VEGF. The method is suitable for use with women undergoing treatment by any of the assisted reproductive technologies, such as those involving the transfer of embryos such as in vitro fertilisation (IVF) and variants including IVF-ICSI (intracytoplasmic spenn injection) and m vitro maturation (1VM) treatments, as well as intrauterine-insemination (IUI) therapy. However, the method is also applicable for women wanting to improve their prospects of pregnancy through natural conception.
摘要:
The invention discloses a method of producing a plant secondary metabolite of interest,comprising: (a) cultivating by suspension culture in a suitable nutrient medium plant cells that produce the secondary metabolite; (b) including within the suspension culture an amount of adsorbent and one or more elicitor agents suitable to increase production of the secondary metabolite; (c)recovering the secondary metabolite from the suspension culture. In a preferred emobidment the invention discloses a method of producing a stilbene plant secondary metabolite of interest, comprising: (a) cultivating by suspension culture in a suitable nutrient medium plant cells that produce a stilbene secondary metabolite; (b) including within the suspension culture an amount of adsorbent and one or more elicitor agents suitable to increase production of the stilbene; (c) recovering the stilbene from the suspension culture.
摘要:
The invention concerns a process and a reagent for the determination of ions in fluids, wherein the influence of these ions on the activity of an enzyme is measured. The ions for example are sodium, potassium, calcium, magnesium, manganese, lithium, lead, zinc, copper, iron or other heavy metals or non-metallic ions comprising chloride, bicarbonate, protons, ammonium substances that give rise to ammonium. The enzymes which are used may be for example a transferase, a hydrolase, an oxidoreductase or a lyase. An essential part of the invention is a method to exclude interferences by ions by masking the interfering ions with a binding agent.
摘要:
A method of forming a catalyst support by heat treatment of gamma -alumina; a supported primary catalyst comprising iron and a modifier element, in particular a rare earth metal or lanthanum, for conversion of a feed stream of carbon monoxide and hydrogen into hydrocarbons to increase the proportion of C2 - C8 hydrocarbons and the proportion of 1-alkenes in the product; and a secondary catalyst comprising an intermediate oxide of tungsten for the production of branched chain alkenes from straight chain alkenes.
