Good tolerance to goat's milk in patients with recurrent aphthous ulcers with increased immunoreactivity to cow's milk proteins.Recurrent aphthous ulcers (RAU) represent a very common, but poorly understood mucosal disorder. The connection between immunity to cow's milk proteins (CMP) and oral diseases was noted earlier. The goal of this study was to determine the prevalence of the increased levels of serum antibodies to goat's milk proteins (GMP), by enzyme-linked immunosorbent assay (ELISA) test, in subjects who have RAU and proven increased immunity to CMP.

Expression of the human granulocyte-macrophage colony stimulating factor (hGM-CSF) gene under control of the 5'-regulatory sequence of the goat alpha-S1-casein gene with and without a MAR element in transgenic mice.Expression of the human granulocyte-macrophage colony-stimulating factor (hGM-CSF) gene under the control of the 5'-regulatory sequence of the goat alpha-S1-casein gene with and without a matrix attachment region (MAR) element from the Drosophila histone 1 gene was studied in four and eight transgenic mouse lines, respectively. Of the four transgenic lines carrying the transgene without MAR, three had correct tissues-specific expression of the hGM-CSF gene in the mammary gland only and no signs of cell mosaicism. The concentration of hGM-CSF in the milk of transgenic females varied from 1.9 to 14 μg/ml. One line presented hGM-CSF in the blood serum, indicating ectopic expression. The values of secretion of hGM-CSF in milk of 6 transgenic lines carrying the transgene with MAR varied from 0.05 to 0.7 μg/ml, and two of these did not express hGM-CSF. Three of the four examined animals from lines of this group showed ectopic expression of the hGM-CSF gene, as determined by RT-PCR and immunofluorescence analyses, as well as the presence of hGM-CSF in the blood serum. Mosaic expression of the hGM-CSF gene in mammary epithelial cells was specific to all examined transgenic mice carrying the transgene with MAR but was never observed in the transgenic mice without MAR. The mosaic expression was not dependent on transgene copy number. Thus, the expected "protective or enhancer effect" from the MAR element on the hGM-CSF gene expression was not observed.

Dynamics of recombinant hG-CSF in transgenic goat: preliminary study in the founder during hormonally induced lactation.This study aimed to characterize the dynamic of human granulocyte colony-stimulating factor (hG-CSF) during artificial lactation in a transgenic founder goat and to assess its potential ectopic expression and health. The female secreted 93.9 to 1,474.6 µg hG-CSF per mL of milk. Two peaks of serum hG-CSF (3,470 and 7,390 pg/mL) were detected in the first half of the lactation. Outside of the lactation, hG-CSF was absent from serum, indicating no ectopic expression. During the treatment to induce lactation, transgenic female presented increased neutrophil and lymphocyte blood counts when compared to nontransgenic female. Despite transient neutrophilia, serum biochemistry profiles indicated normal liver and renal functions. Thus, transgenic goat expressed hG-CSF in quantities sufficient for a commercial bioreactor and remained clinically healthy.

Is it just lactose intolerance?Acquired delayed-onset hypolactasia is a common autosomal recessive condition. Cow's milk allergies, conversely, are less common conditions that may manifest with equivalent symptoms and are able to simulate and/or aggravate lactose intolerance. This study was designed to evaluate the contribution of IgE-mediated cow's milk sensitization to the symptomatology of adult patients with lactose-free diet refractory lactose intolerance. Forty-six adult patients with lactose intolerance and persistent symptoms despite a lactose-free diet underwent skin-prick test to investigate cow's milk, goat's milk, and soy protein-specific-IgE. SDS-PAGE immunoblotting was used to investigate the presence of cow's milk protein-specific IgE. The percentage of patients who had skin reactions to whole cow's milk, alpha-lactalbumin, beta-lactoglobulin, caseins, goat's milk, and soy was 69.5, 36.9, 56.5, 56.5%, 54.3, and 50%, respectively. The percentage of patients with immunoblot-detected IgE specific for alpha-lactalbumin, beta-lactoglobulin, caseins, and bovine serum albumin was 21.7, 63, 67.3, and 2.1%, respectively. IgE-mediated sensitization to cow's milk is a frequent comorbidity in subjects with lactose-free diet refractory lactose intolerance and is worth consideration in patients with this condition.

Hybrid expression cassettes consisting of a milk protein promoter and a cytomegalovirus enhancer significantly increase mammary-specific expression of human lactoferrin in transgenic mice.It is very important to develop an effective, specific, and robust expression cassette that ensures a high level of expression in the mammary glands. In this study, we designed and constructed a series of mammary gland-specific vectors containing a complex hybrid promoter/enhancer by utilizing promoter sequences from milk proteins (i.e., goat β-casein, bovine αs1-casein, or goat β-lactoglobulin) and cytomegalovirus enhancer sequences; vectors containing a single milk protein promoter served as controls. Chicken β-globin insulator sequences were also included in some of these vectors. The expression of constructs was analyzed through the generation of transgenic mice. Enzyme-linked immunosorbent assay (ELISA) analysis revealed that the hybrid promoter/enhancer could drive the expression of recombinant human lactoferrin (rhLF) cDNA at high levels (1.17-8.10 mg/ml) in the milk of transgenic mice, whereas control promoters achieved a very low rhLF expression (7-40 ng/ml). Moreover, the expression of rhLF was not detected in the serum or saliva of any transgenic animal. This result shows that all constructs, driven by the hybrid promoter/enhancer, had high mammary gland-specific expression pattern. Together, our results suggest that the use of a hybrid promoter/enhancer is a valuable alternative approach for increasing mammary-specific expression of recombinant hLF in a transgenic mouse model.

Efficiency of donor cell preparation and recipient oocyte source for production of transgenic cloned dairy goats harboring human lactoferrin.The objective was to investigate the effects of the transgenic donor cell synchronization method, oocyte sources, and other factors, on production of hLF-gene nucleus transfer dairy goats. Three transfected cell lines from ear biopsies from three 3-mo-old Saanen dairy goats (designated Number 1, Number 2, and Number 3, respectively) were selected as karyoplast donors for somatic cell nuclear transfer (SCNT) after detailed identification (including PCR and sequencing of PCR products). In donor cell cycle synchronization studies, the apoptosis rate of hLF transgenic fibroblasts was not different (P > 0.05) after 3 days of serum starvation or 2 days of contact inhibition. Additionally, there was no effect (P > 0.05) on developmental capacity of reconstructed embryos; however, the kidding rate of recipients in the serum starvation group was higher than that in the contact inhibition group (18 vs. 0%, respectively). The production efficiency of the transgenic cloned goats using donor cells from the Number 1 dairy goat cell line was higher than those using the Number 2 and the Number 3 cell lines (kidding rates were 18, 2, and 0%, respectively, P < 0.05). The oocyte source did not significantly affect the pregnancy rate of hLF-transgenic cloned dairy goats, but more fetuses were aborted when using in vitro matured oocytes compared to in vivo matured oocytes. In summary, utilizing transfected 3-mo-old dairy goat fibroblasts as donor cells, seven live offspring were produced, and the hLF gene was successfully integrated. This study provided additional insights into preparation of donor cells and recipient oocytes for producing transgenic cloned goats through SCNT.

A synthetic Protein G adsorbent based on the multi-component Ugi reaction for the purification of mammalian immunoglobulins.Numerous efforts have been devoted to develop synthetic affinity ligands mimicking natural immunoglobulin-binding proteins, such as Proteins A and L, in order to overcome intrinsic drawbacks involving their high cost and acidic pH elution. However, few reports have focused on a Protein G mimic. This work describes the use of the solid phase multi-component Ugi reaction to generate a low cost, rationally designed, affinity ligand to mimic Protein G for the purification of mammalian immunoglobulins, including the heavy-chain only camelid IgGs, with effective elution at neutral pH. An aldehyde-functionalised Sepharose™ resin constituted one component (aldehyde) of the four-component Ugi reaction, whilst the other three components (a primary or secondary amine, a carboxylic acid and an isonitrile) were varied to generate a tri-substituted Ugi scaffold, with a wide range of functionality, suitable for mimicking peptides for immunoglobulin purification. Ligand A2C11I1 was designed to mimic Asn35 and Trp43 of Protein G (PDB: 1FCC) and in silico docking into the Fc domain showed a key binding interface closely resembling native Protein G. This candidate ligand demonstrated affinity towards IgGs derived from human, cow, goat, mouse, sheep, pig, rabbit and rat serum, chicken IgY and recombinant camelid Fc domain, out of which cow and sheep IgG demonstrated 100% binding under the conditions selected. Preparative chromatography of IgG from human serum under a standardised buffer regime eluted IgG of ∼65% purity, compared to ∼62% with Protein G. This adsorbent achieved highest elution of IgG at neutral pH (0.1M sodium phosphate pH 7.0, 30%, v/v, ethylene glycol), an advantage for purifying antibodies sensitive to extremes of pH. The ligand demonstrated a static binding capacity of 24.6 mg Ig G ml⁻¹ resin and a dissociation constant (K(d)) of 4.78 × 10⁻⁶ M. The solid phase Ugi scaffold provides a strategy to develop pseudo-biospecific ligands to purify immunoglobulins and other potentially high-value biotherapeutic proteins.

Comparison of three immunosensor methods (surface plasmon resonance, screen-printed and classical amperometric immunosensors) for immunoglobulin G determination in human serum and animal or powdered milks.Within the framework of research carried out by our team aimed at developing new immunological methods to determine proteins such as immunoglobulins G in different biological matrixes, for instance, serum and milk, tests were performed on several immunosensors based on different transducer types, i.e. amperometric (classical or screen-printed) electrodes for hydrogen peroxide. Lastly the feasibility of constructing immunosensors based on surface plasmon resonance (SPR) was investigated. "Competitive" immunological procedures were used in the first two cases. Conversely, the surface plasmon resonance transduction technique allowed a "direct" measurement. Applications were performed on human serum, powdered milks for babies and particularly on several animal milks, in the case of buffalo milk seeking a routine control method to identify possible inflammatory affections in the animals.

Serial kinetics of the antibody response against the complete Brucella melitensis ORFeome in focal vertebral brucellosis.Human brucellosis is a common zoonosis worldwide. Here we present a case of focal vertebral brucellosis in a 71-year-old Mexican-American woman who contracted infection from unpasteurized goat milk. Standard agglutination serology was negative; the diagnosis was established by the isolation of Brucella melitensis from abscess fluid. A B. melitensis protein microarray comprised of nearly all proteins encoded by the bacterial genome was used to determine the kinetics of this patient's antibody responses to the complete collection of open reading frames existing in the genome (ORFeome). Three patterns of antibody responses against B. melitensis antigens were seen for serum samples obtained on days 0 (pretreatment), 14, 49, 100, and 180: (i) stable titers over time, (ii) a steady fall in titers, and (iii) an initial rise in titers followed by declining titers. Sera from this patient with chronic brucellosis recognized some of the same B. melitensis proteins as those recognized by sera from acute/subacute, blood culture-positive brucellosis patients but also recognized a distinct set of proteins. This study is the first to determine the kinetics of the human antibody responses to the complete repertoire of proteins encoded by a bacterial genome and demonstrates fundamentally different immunopathogenetic mechanisms between acute human brucellosis and chronic human brucellosis. While an extension of these findings to a larger patient population is necessary, these findings have important clinical and diagnostic implications and lead toward new insights into the fundamental immunopathogenesis of brucellosis.
