A well-developed, functional immune system is paramount to combat harmful attack from pathogenic organisms and prevent infectious diseases. Newborn animals and humans have only limited immunity upon birth, but their immune functions are expected to develop within weeks to months and eventually to reach a maturity that will provide full protection. Despite the importance of immune activity in animal and human health management, there is no convenient test available that allows for rapid assessment of the state of immune function in non-laboratory settings.

Titin has long been recognized as a mechanical protein in muscle cells that has a main function as a molecular spring in the contractile units, the sarcomeres. Recent work suggests that the titin spring contributes to muscle contraction in a more active manner than previously thought. In this review, we highlight this property, specifically the ability of the immunoglobulin-like (Ig) domains of titin to undergo unfolding-refolding transitions when isolated titin molecules or skeletal myofibrils are held at physiological force levels.

High-throughput and low-cost detection of mycotoxins in complex matrices is becoming increasingly urgent but still challenged for ultra-sensitive analyses. Here we reported a green and practical cytometric micro-bead magnetic suspension array (CBMSA) strategy for rapid and economical detection of aflatoxin B1 (AFB1) in multiple batches of lotus seeds samples. The protocol included the fabrication of the suspension array chips by immobilizing the biotin-modified bovine serum albumin-AFB1 (antigen) onto the surface of streptavidin-coated magnetic micro-beads in a multi-wells array, the indirect immuno-competition of antigen and target of AFB1 in lotus seed samples with the specific antibodies, the rapid magnetic separation regardless complex pretreatment steps, and the ultra-sensitive fluorescence detection of fluorescein isothiocyanate labeled goat anti-mouse immunoglobulin G (FITC-IgG) probes.

The bovine whey consists of more than 200 different types of proteins, of which β-lactoglobulin, α-lactalbumin, serum albumin, immunoglobulins and lactoferrin predominate. However, their concentrations are not stable due to the existence of protein dynamics during a transition from colostrum secretion to mature milk. To evaluate the dynamics of whey proteins of Jersey cows during a colostral phase and first month of lactation and an influence of the number of lactations, 268 milk samples from 135 Jersey cows were selected through a clinical evaluation.

The process of agglutination causes firm cream layers in bovine milk, and a functioning agglutination mechanism is paramount to the quality of non-homogenized milks. The phenomenon is not well-described, but it is believed to occur due to interactions between immunoglobulins (Ig) and milk fat globules. For the first time, this paper demonstrates how the process of agglutination can be visualized using confocal laser scanning microscopy, rhodamine red and a fluoresceinisothiocynat-conjugated immunoglobulin M antibody.

Molecular-based allergy diagnosis for the assessment of a patient immunoglobulin E (IgE) sensitization profile at the molecular level uses allergen molecules (also referred to as allergen components), which may be well-defined, highly purified, natural allergen components or recombinant allergens. Modern immunoassay methods used for the detection of specific IgE against aeroallergen components are either singleplex (such as the fluorescence enzyme immunoassay with capsulated cellulose polymer solid-phase coupled allergens, the enzyme-enhanced chemiluminescence immunoassay and the reversed enzyme allergosorbent test, with liquid-phase allergens), multiparameter (such as the line blot immunoassay for defined partial allergen diagnostics with allergen components coating membrane strips) or multiplex (such as the microarray-based immunoassay on immuno solid-phase allergen chip, and the two new multiplex nanotechnology-based immunoassays: the patient-friendly allergen nano-bead array, and the macroarray nanotechnology-based immunoassay used as a molecular allergy explorer). The precision medicine diagnostic work-up may be organized as an integrated "U-shape" approach, with a "top-down" approach (from symptoms to molecules) and a "bottom-up" approach (from molecules to clinical implications), as needed in selected patients.

The intraerythrocytic parasite is the number 1 cause of transfusion-transmitted infection and can induce serious, often life-threatening complications in immunocompromised individuals including transfusion-dependent patients with sickle cell disease (SCD). Despite the existence of strong long-lasting immunological protection against a second infection in mouse models, little is known about the cell types or the kinetics of protective adaptive immunity mounted following infection, especially in infection-prone SCD that are thought to have an impaired immune system. Here, we show, using a mouse infection model, that infected wild-type (WT) mice mount a very strong adaptive immune response, characterized by (1) coordinated induction of a robust germinal center (GC) reaction; (2) development of follicular helper T (T) cells that comprise ∼30% of splenic CD4 T cells at peak expansion by 10 days postinfection; and (3) high levels of effector T-cell cytokines, including interleukin 21 and interferon γ, with an increase in the secretion of antigen (Ag)-specific antibodies (Abs).

Detailed structural characterization of protein biopharmaceuticals is a critical step in research and development; however, this step is often hampered by the structural complexities associated with glycosylation. Most protein biopharmaceuticals are modified with structurally heterogeneous and dynamic oligosaccharides which govern the physicochemical properties, functionality, pharmacokinetics, and potential pathogenicity of these glycoproteins. Considering this, we have developed a structural biological approach to describe the dynamic three-dimensional structures and interactions of glycoproteins as biopharmaceuticals. Read More
