Development of a Nomogram Based on Transcriptional Signatures, IFN-γ Response and Neutrophils for Diagnosis of Tuberculosis.

Purpose: Tuberculosis (TB) is a major global health threat and its diagnosis remains challenging. This study aimed to develop a nomogram that incorporated peripheral blood transcriptional signatures and other blood tests for the diagnosis of tuberculosis.

Patients And Methods: Patients with TB, patients with other definite pulmonary diseases (OPD), individuals with latent tuberculosis infection (LTBI), and healthy controls (HC) were retrospectively enrolled between May 2017 and April 2018.

Evaluation of IFIT3 and ORM1 as Biomarkers for Discriminating Active Tuberculosis from Latent Infection.

Objective: Current commercially available immunological tests cannot be used for discriminating active tuberculosis (TB) from latent TB infection. To evaluate the value of biomarker candidates in the diagnosis of active TB, this study aimed to identify differentially expressed genes in peripheral blood mononuclear cells (PBMCs) between patients with active TB and individuals with latent TB infection by transcriptome sequencing.

Methods: The differentially expressed genes in unstimulated PBMCs and in Mycobacterium tuberculosis (Mtb) antigen-stimulated PBMCs from patients with active TB and individuals with latent TB infection were identified by transcriptome sequencing.

Mesenchymal-epithelial Transition Factor Regulates Monocyte Function during Mycobacterial Infection via Indoleamine 2,3-dioxygenase.

Objective: Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB), causes an estimated 1.6 million human deaths annually, but the pathogenesis of TB remains unclear. Immunity plays a critical role in the onset and outcome of TB.

[Prepared the monoclonal antibody associated with hepatocellular carcinoma and analyzed its epitope].

Aim: To prepare the monoclonal antibodies associated with hepatocellular carcinoma (HCC) for diagnosis.

Methods: 3 BALB/c mice were immunized with high metastasis characteristic HCC cells (HCCLM-6). The splenocytes from the immunized mice were fused with murine myeloma cells (Sp2/0).

Recombinant heat shock protein 65 carrying hepatitis B core antigen induces HBcAg-specific CTL response.

Many studies have provided evidence that heat shock protein 65 (Hsp65) can elicit potent specific cellular adaptive immune responses (e.g. CD8(+) cytotoxic T-cell effectors or classic CTLs) based on their ability to chaperone antigenic peptides.

Construction and evaluation of anti-gastrin immunogen based on P64K protein.

Aim: To construct two kinds of anti-gastrin immunogen based on P64K protein from Neisseria meningitids and to compare their immunogenic effect.

Methods: G17P64K gene was cloned and ligated into pET28a plasmid, then transformed into BL21(DE3). After inoculation of LB medium and IPTG induction, the recombinant protein was solubly expressed at a high level.

Secretory expression and characterization of a recombinant-deleted variant of human hepatocyte growth factor in Pichia pastoris.

Aim: To study the secretory expression of human hepatocyte growth factor (hdHGF) gene in Pichia pastoris.

Methods: The full-length gene of human cDNA encoding the deleted variant of hdHGF was cloned by RT-PCR and overlapping-fragment PCR technique using mRNA of human placenta as a template. The cloned hdHGF cDNA was inserted into the Escherichia coli-yeast shuttle vector of pPIC9.

[Purification and activity assay of HSA-AX15 (R13K) fusion protein expressed in Pichia pastoris].

To increase the in vivo half-life of human CNTF mutein AX15 (R13K), HSA-AX15 (R13K) fusion protein was constructed by the fusion of the C-terminus of HSA to the N-terminus of AX15 (R13K) via an 11 amino acids linker. HSA-AX15 (R13K) fusion protein was purified to homogeneity by cation exchange chromatography, reverse phase chromatography and gel filtration after expressed in pichia pastoris. TF-1 cell survival bioassay showed the biological activity of AX15 (R13K) was not affected by the fusion to HSA.
