The invention provides a construction method of a cell model for detecting pyrogens, the cell model and a pyrogen detection kit. The cell model utilizes specific locations of CRISPR / CAS9 induced genomes to form double-bond fission, TLR4 and CD14-MD2 are knocked into two chromosomes of a cell line respectively by the aid of the homologous recombination repair principle, green fluorescence GFP and red fluorescence RFP are respectively used for tracing finally successfully constructed TLR4 / CD14 / MD2 fixed-point knocked-in fluorescent tracer cell models, and the LPS stimulating cell model can detect release of IL-6 and TNF-a cytokines by means of ELISA, Western Blot, mass spectrum and immunomagnetic beads. The cell model is good in stability and high in sensitivity, and the lowest detectable limit can reach 0.005EU / mL and is far lower than 0.025EU / mL of the Tachypleus Amebocyte Lysate method.

The invention discloses a method for amplification and activation of NK cells by K562 cells. The method comprises that through synergism of K562 cells transfected by transmembrane interleukin 21, CD14, CD19, CD86 and CD137, and low-concentration interleukin 2, NK cells are subjected to directed amplification and activation. Compared with the existing similar compounds, the compound provided by the invention has a stronger lymphocyte amplification and activation capability and higher efficiency. The method has wide prospects in immunological therapy.

A genetic marker of food allergy is disclosed. The marker comprises variants of IL-4 receptor alpha, IL13 and CD14.

Efficacy of a therapeutic to enhance antitumor immunity in a patient is predicted, where the therapeutic is one that targets an immunomodulatory leukocyte membrane protein (ILMP) to enhance immune activity. Peripheral blood sample from the patient is tested for levels of monocytes having specific cell surface markers (CD14+, HLA-DRlow) prior to treatment. Low levels of monocytes of this type (PBM14+HLA-DRlow) indicate a greater likelihood of therapeutic efficacy. In specific exemplary embodiments of the invention, the therapeutic is an antibody to CTLA4, such as ipilimumab or tremelimumab.

A protein comprising (I) an anti-CD14 antibody or its active fragment, or a derivative thereof and (II) an inhibitor for a protease, or its active fragment, or a derivative thereof is provided.

The invention discloses a kit for detecting the mycobacterium tuberculosis infection and monitoring a clinical treatment effect. The kit provided by the invention comprises a specific antibody, namely an IP-10 antibody and / or CD14 antibody, an antigen irritant and a positive contrast irritant. The kit disclosed by the invention can be used for diagnosing an active tuberculosis patient or a tuberculosis latent infection patient and is not affected by BCG (bacillus calmette-guerin) inoculation. The sensitivity and the specificity of the kit for diagnosing the active tuberculosis patient are higher than those of a commercial T-SPOT.TB kit and can be up to 100 percent. After the antituberculosis therapy is performed for 1 month, the detection rates of over 80 percent of clinical tuberculosis patients are converted to be negative, so that the kit can be used for detecting the clinical antituberculosis treatment effect.

This invention concerns a liposome comprising lipids and at least one active ingredient, wherein at least one of the lipids is a cationic lipid; said liposome exhibiting a net positive charge at physiological conditions at which said liposome preferentially adheres to monocytes in freshly drawn blood when compared to adherence to granulocytes, T-lymphocytes, B-lymphocytes and / or NK cells in freshly drawn blood, to a lipid-based pharmaceutical composition comprising said liposomes and their use in monocytic associated prophylaxis, treatment or amelioration of a condition such as cancer, an infectious disease, an inflammatory disease, an autoimmune disease or allergy.

There are provided a soluble CD14 antigen which is a novel in vivo protein useful as a marker for diagnosing sepsis and has the following characteristic features 1) to 3):1) a molecular weight of 13±2 kDa when measured by SDS-PAGE under non-reducing conditions;2) an amino acid sequence in which the amino acid sequence of SEQ ID NO:1 is present on its N terminal; and3) ability to specifically bind to an antibody prepared by using a peptide comprising 16 amino acid residues described in SEQ ID NO:2 for the antigen; and a recombinant soluble CD14 fragment.

Methods of isolating and cryopreserving progenitors from human liver are disclosed which include processing human liver tissue to provide a substantially single cell suspension comprising progenitors and non-progenitors of one or more cell lineages found in human liver; subjecting the suspension to a debulking step, which reduces substantially the number of non-progenitors in the suspension, and which provides a debulked suspension enriched in progenitors exhibiting one or more markers associated with at least one of the one or more cell lineages; and selecting from said debulked suspension those cells, which themselves, their progeny, or more mature forms thereof express one or more markers associated with at least one of the one or more cell lineages. Among these markers are CD14, CD34, CD38, CD45, and ICAM. Hepatic progenitors are characterized as being 6-15μ in diameter, diploid, glycophorin A−, CD45−, AFP+++, ALB+, ICAM+, and with subpopulations varying in expression of CD14+. CD34++, CD38++, CD117+. These progenitor subpopulations have characteristics expected for cells that are particularly useful in liver cell and gene therapies and for establishing bioartificial organs.

Improved methods, reagents, and kits for quantitation of HLA-DR and / or CD11b expression on peripheral blood cells are presented. Inclusion of a lysosomotropic amine, such as chloroquine, during staining stabilizes HLA-DR and CD11b expression. Use of a novel anti-CD14 conjugate, anti-CD14-PerCP / CY5.5, permits the ready discrimination of monocytes. The improved methods, reagents, and kits may be used to assess immune competence, and to direct and monitor immunostimulatory therapies in septic patients exhibiting monocyte deactivation.
