Abstract
Lung cancer is a dangerous disease that is lacking in an ideal therapy. Here, we evaluated the anti-lung cancer effect in nude mice of a fully human single-chain antibody (scFv) against the associated antigen 7 transmembrane receptor (Ts7TMR), which is also called G protein-coupled receptor, between A549 cells and Trichinella spiralis (T. spiralis). Our data showed that anti-Ts7TMR scFv could inhibit lung cancer growth in a dose-dependent manner, with a tumour inhibition rate of 59.1%. HE staining did not reveal any obvious tissue damage. Mechanistically, immunohistochemical staining revealed that the scFv down-regulated the expression of PCNA and VEGF in tumour tissues. Overall, this study found that anti-Ts7TMR scFv could inhibit A549 lung cancer growth by suppressing cell proliferation and angiogenesis, which may provide a new strategy for treating lung cancer.

Abstract
Non-small cell lung cancer (NSCLC) has a long history of defying traditional cytotoxic treatment. Significant advancements in biotechnology, cancer biology, and immunotherapy have provided new insights that have altered the landscape for the management of NSCLC, clearing the way for a new era of pharmaceuticals in the form of monoclonal antibodies and their fragments. Antibody fragments are superior to monoclonal antibodies because of their small size, which allows them to penetrate cells and tissues effectively. When combined with functional nanocarriers, antibody fragments can target cancer cells while offering improved efficacy and fewer off-target effects. We discuss current topics of interest including anti-CTLA-4 mAbs, Talactoferrin alfa (TLF), and the CYFRA 21-1 biomarker, with brief insights into its novel detection system.

Abstract
Introduction: Cancer immunotherapy with monoclonal antibodies (mAbs) has become a therapy with great potential nowadays. It is based on the affinity of antibodies to bind to specific molecules, thus inhibiting the growth and spread of cancer. There is a wide variety of mAbs with differentiated mechanisms and enormous clinical benefits. However, different immunotherapeutic alternatives have emerged due to their limitations, such as the long duration of organ toxicity and the inability to penetrate intracellularly. This mini-review will discuss the emerging alternatives of cancer immunotherapies based on mAbs.
Bispecific antibodies (BsAbs): Antibodies designed to bind to two epitopes of an antigen.
Antibody fragments: Fragments of the Fab region generated from the variable region of IgG and IgM and a scFv.
Antibody-drug conjugates (ADCs): Administration of mAbs and a toxin of high specificity for a tumour target.
Nanobodies (or nanocomponents): Small fragments of antibody heavy chain.
Intrabodies (or intracellular antibodies): Antibodies that are expressed intracellularly and synthesised inside cells by retroviral delivery systems.
Stereospecific and catalytic mAbs: Antibodies that recognise the 3D configurations of target molecules.
Combination immunotherapies: Therapies that combine cytokines with tumour-targeted mAbs.
Small molecule immunotherapeutics: Small molecule drugs that can stimulate intracellular pathways primarily involved in immune cell checkpoints and bind to mAb-like targets.
Conclusion: These new varieties of immunotherapy present significant advantages, but future research should continue to improve their efficacy and safety and identify new biomarkers.

Abstract
Microcystin-LR (MC-LR) is a high-toxic biohazard that pollutes ecological environment and agroproducts. In this study, a newly recombined genetically engineered antibody (AVHH-MVH) with higher thermal stability and binding activity was designed by chain shuffling and based on our previously obtained anti-MC-LR scFv and nanobody. Based on AVHH-MVH template, a capacity of 8.99 × 105 CFU/mL of phage display AVHH-MVH mutagenesis library was constructed by site-directed mutagenesis in MVH-CDR3 region, and then used for ultrasensitive mutants screening. Afterwards, a total of five positive AVHH-MVH mutants were isolated from the mutagenesis library, and their binding activity was higher than AVHH-MVH for MC-LR. The AVHH-MVH mutant 3 was cloned into pET-25b vector for soluble expression, and the concentration of target protein expressed in culture system was 43.5 mg/L. An indirect competitive enzyme-linked immunosorbent assay (IC-ELISA) was established based on purified AVHH-MVH mutant 3 protein, and it showed ultrasensitive binding activity for MC-LR with the detection limit of 0.0075 μg/L, which was far below the maximum residue limit standard of 1.0 μg/L in drinking water proposed by World Health Organization. The established IC-ELISA shows good accuracy, repeatability, stability and applicability for MC-LR spiked samples, and it is promising for MC-LR ultrasensitive monitoring.

Abstract
Multifunctional matrix protein (M) of rabies virus (RABV) plays essential roles in the pathogenesis of rabies infection. Identification of M protein interacting partners in target hosts could help to elucidate the biological pathways and molecular mechanisms involved in the pathogenesis of this virus. In this study, two-dimensional Far-western blotting (2D-Far-WB) technique was applied to find possible matrix protein partners in the rat brainstem. Recombinant RABV M was expressed in Pichia pastoris and was partially purified. Subsequently, 2D-Far-WB-determined six rat brainstem proteins interacted with recombinant M proteins that were identified by mass spectrometry. Functional annotation by gene ontology analysis determined these proteins were involved in the regulation of synaptic transmission processes, metabolic process and cell morphogenesis-cytoskeleton organization. The interaction of viral M protein with selected host proteins in mouse Neuro-2a cells infected with RABV was verified by super-resolution confocal microscopy. Molecular docking simulations also demonstrated the formation of RABV M complexes. However, further confirmation with co-immunoprecipitation was only successful for M-actin cytoplasmic 1 interaction. Our study revealed actin cytoplasmic 1 as a binding partner of M protein, which might have important role(s) in rabies pathogenesis.

Abstract
The heat shock protein (Hsps) superfamily, also known as molecular chaperones, are highly conserved and present in all living organisms and play vital roles in protein fate. The HspA1A (Hsp70-1), called Hsp70 in this review, is expressed at low or undetectable levels in most unstressed normal cells, but numerous studies have shown that diverse types of tumor cells express Hsp70 at the plasma membrane that leads to resistance to programmed cell death and tumor progression. Hsp70 is released into the extracellular milieu in three forms including free soluble, complexed with cancer antigenic peptides, and exosome forms. Therefore, it seems to be a promising therapeutic target in human malignancies. However, a great number of studies have indicated that both intracellular and extracellular Hsp70 have a dual function. A line of evidence presented that intracellular Hsp70 has a cytoprotective function via suppression of apoptosis and lysosomal cell death (LCD) as well as that extracellular Hsp70 can promote tumorigenesis and angiogenesis. Other evidence showed intracellular Hsp70 can promote apoptosis and membrane-associated/extracellular Hsp70 can elicit antitumor innate and adaptive immune responses. Given the contradictory functions, as a "double agent," could Hsp70 be a promising tool in the future of targeted cancer therapies? To answer this question, in this review, we will discuss the functions of Hsp70 in cancers besides inhibition and stimulation strategies for targeting Hsp70 along with their challenges.

Abstract
Proprotein convertase subtilisin/kexin type 9 (PCSK9), as a vital modulator of low-density lipoprotein cholesterol (LDL-C) , is raised in hepatocytes and released into plasma where it binds to LDL receptors (LDLR), leading to their cleavage. PCSK9 adheres to the epidermal growth factor-like repeat A (EGF-A) domain of the LDLR which is confirmed by crystallography. LDLR expression is adjusted at the transcriptional level through sterol regulatory element binding protein 2 (SREBP-2) and at the post translational stages, specifically through PCSK9, and the inducible degrader of the LDLR PCSK9 inhibition is an appealing new method for reducing the concentration of LDL-C. In this review the role of PCSK9 in lipid homeostasis was elucidated, the effect of PCSK9 on atherosclerosis was highlighted, and contemporary therapeutic techniques that focused on PCSK9 were summarized. Several restoration methods to inhibit PCSK9 have been proposed which concentrate on both extracellular and intracellular PCSK9, and they include blockage of PCSK9 production by using gene silencing agents and blockage of it's binding to LDLR through antibodies and inhibition of PCSK9 autocatalytic processes by tiny molecule inhibitors.
