Abstract
Background Identification of genetic mechanisms and idiosyncrasies at the breed-level can provide valuable information for potential use in evolutionary studies, medical applications, and breeding of selective traits. Here, we analyzed genomic data collected from 136 Korean Native cattle, known as Hanwoo, using advanced statistical methods. Results Results revealed Hanwoo-specific protein domains which were largely characterized by immunoglobulin function. Furthermore, domain interactions of novel Hanwoo-specific genes reveal additional links to immunity. Novel Hanwoo-specific genes linked to muscle and other functions were identified, including protein domains with functions related to energy, fat storage, and muscle function that may provide insight into the mechanisms behind Hanwoo cattle’s uniquely high percentage of intramuscular fat and fat marbling. Conclusion The identification of Hanwoo-specific genes linked to immunity are potentially useful for future medical research and selective breeding. The significant genomic variations identified here can crucially identify genetic novelties that are arising from useful adaptations. These results will allow future researchers to compare and classify breeds, identify important genetic markers, and develop breeding strategies to further improve significant traits.

Abstract
Therapeutic antibodies provide important tools in the "medicine chest" of today's clinician for the treatment of a range of disorders. Typically monoclonal or polyclonal antibodies are administered in large doses, either directly or indirectly into the circulation, via a systemic route which is well suited for disseminated ailments. Diseases confined within a specific localized tissue, however, may be treated more effectively and at reduced cost by a delivery system which targets directly the affected area. To explore the advantages of the local administration of antibodies, we reviewed current alternative, non-systemic delivery approaches which are in clinical use, being trialed or developed. These less conventional approaches comprise: (a) local injections, (b) topical and (c) peroral administration routes. Local delivery includes intra-ocular injections into the vitreal humor (i.e. Ranibizumab for age-related macular degeneration), subconjunctival injections (e.g. Bevacizumab for corneal neovascularization), intra-articular joint injections (i.e. anti-TNF alpha antibody for persistent inflammatory monoarthritis) and intratumoral or peritumoral injections (e.g. Ipilimumab for cancer). A range of other strategies, such as the local use of antibacterial antibodies, are also presented. Local injections of antibodies utilize doses which range from 1/10th to 1/100th of the required systemic dose therefore reducing both side-effects and treatment costs. In addition, any therapeutic antibody escaping from the local site of disease into the systemic circulation is immediately diluted within the large blood volume, further lowering the potential for unwanted effects. Needle-free topical application routes become an option when the condition is restricted locally to an external surface. The topical route may potentially be utilized in the form of eye drops for infections or corneal neovascularization or be applied to diseased skin for psoriasis, dermatitis, pyoderma gangrenosum, antibiotic resistant bacterial infections or ulcerated wounds. Diseases confined to the gastrointestinal tract can be targeted directly by applying antibody via the injection-free peroral route. The gastrointestinal tract is unusual in that its natural immuno-tolerant nature ensures the long-term safety of repeatedly ingesting heterologous antiserum or antibody materials. Without the stringent regulatory, purity and clean room requirements of manufacturing parenteral (injectable) antibodies, production costs are minimal, with the potential for more direct low-cost targeting of gastrointestinal diseases, especially with those caused by problematic antibiotic resistant or toxigenic bacteria (e.g. Clostridium difficile, Helicobacter pylori), viruses (e.g. rotavirus, norovirus) or inflammatory bowel disease (e.g. ulcerative colitis, Crohn's disease). Use of the oral route has previously been hindered by excessive antibody digestion within the gastrointestinal tract; however, this limitation may be overcome by intelligently applying one or more strategies (i.e. decoy proteins, masking therapeutic antibody cleavage sites, pH modulation, enzyme inhibition or encapsulation). These aspects are additionally discussed in this review and novel insights also provided. With the development of new applications via local injections, topical and peroral routes, it is envisaged that an extended range of ailments will increasingly fall within the clinical scope of therapeutic antibodies further expanding this market.

Abstract
BACKGROUND AND OBJECTIVES Intravenous immunoglobulin (IVIG) is used for an increasingly diverse number of therapeutic applications as an immunomodulation drug. Although it has demonstrated therapeutic effectiveness, the mechanism of action of IVIG in these disorders is poorly understood; this lack of understanding complicates rational clinical application and reimbursement for 'off-label' use. MATERIALS AND METHODS Selected literature on the clinical use of IVIG as an immunomodulation drug is reviewed. We present a brief description of DNA microarray and protein microarray technology and the application of such technologies to the study of immune system cells. The several studies on the application of DNA microarray technology to study gene expression in response to IVIG are presented. RESULTS There is increasing data on the use of DNA microarray and protein microarray technology to study gene expression in immune system cells including T cells, B cells, macrophages, and leucocytes. There is less information on the effect of IVIG on gene expression in immune system cells. However, there is sufficient information available to suggest that this is a practical approach with the caveat that such work will require careful experimental design and clear definition of the normal population. CONCLUSIONS DNA and protein microarray assays can be used to (i) provide rational indications for the clinical use of IVIG, (ii) provide for specific analysis of raw material and end product IVIG in screening for content related to immunomodulation, and (iii) accelerate the development of next generation products which would be more focused and/or targeted therapeutics.

Abstract
Probiotics and bovine colostrums had been proven to be beneficial for human health. Lactobacillus rhamnosus ZDY114 and anti-Helicobacter pylori bovine colostrums were used for the preparation of microecological additives, and their synergistic antidigestion effect in the simulated gastrointestinal tract (in vitro) was investigated. Either L. rhamnosus or purified IgG from immune colostrums was very sensitive in simulated gastric environment and slightly sensitive in simulated intestinal tract. No viable counts were recovered from the solution of dissolved freeze-dried powder (7.14 log(10) CFU/ml) of L. rhamnosus when digested at pH 3.0 with pepsin for 30 min. Activity of purified IgGs from immune colostrums could not be detected when digested at pH 3.0 with pepsin for 30 min; 29% titer could be detected when digested at pH 8.0 with trypsin for 5 h. The IgGs in nonpurified immune colostrums presented stronger resistance against gastrointestinal digestion than purified IgGs. Moreover, the combination of L. rhamnosus ZDY114 and immune colostrums strengthened their antidigestion ability. Even under pH 3.0, 4.0 with pepsin, the titer of anti-HP IgG maintained above 123 and 83.3%, respectively. Similarly, that titer was above 93.3% when digested at pH 8.0 with trypsin for 4.5 h. In conclusion, L. rhamnosus and anti-Helicobacter pylori bovine colostrums had synergistic antidigestion effect in simulated gastrointestinal tract (in vitro).

Abstract
The synergistic effects of Lactobacillus rhamnosus and bovine colostrums on the immunity of mice in vivo and in vitro were investigated. Eight- to ten-week-old mice were used for two series experiments; one part of mice were immunocompromised by intraperitoneal injections of cyclophosphamide. In series I, immunocompromised mice were continuously fed with diet A (L. rhamnosus ZDY114 5 x 10(7) CFU/kg), B (bovine colostrums 0.5 g/kg), C (combination of diet A and B), and D (sterile saline) for 4 weeks and killed. Thereof, phagocytosis ratio and index of macrophage to chicken red blood cells in abdominal cavity and lymphocyte transformation rate were determined. In series II, both normal and immunocompromised mice were used to investigate the in vitro stimulation of lymphocyte proliferation by substances from the overnight culture of L. rhamnosus ZDY114 by the MTT colorimetric method. Compared with diet D, in the diet A, B, and C groups, the phagocytosis ratio of macrophages increased by 1.63, 1.54, and 2.3-fold, respectively, and the lymphocyte transformation ratio by 1.78, 2.08, and 2.35-fold, respectively. In vitro test with MTT showed that 3, 10, 50 kD substances from the overnight culture of L. rhamnosus ZDY114 significantly increased the growth of lymphocyte by 1.63, 1.53, and 1.34-fold, respectively. In conclusion, L. rhamnosus and bovine colostrums can enhance the functions of immune system supported by lymphocytes and peritoneal macrophages either in vivo or in vitro.

Abstract
Human and humanised antibodies are now poised to become a major new class of protein-based therapeutic agents. A significant fraction of new drugs in clinical testing (approximately 20% in 2002) are antibody classes. Monoclonal antibodies (mAbs) with high affinities against newly discovered disease targets, both cellularly and extracellularly, are now clinically proven to elicit high bioactivities against numerous diseases, including tumours, infections, asthma, inflammation, arthritis and osteoporosis. Clinical humanised antibody delivery is typically intravenous, with large multiple doses (grams) required for systemic volumes of distribution. Due to the relatively high costs of both this drug type, and its common mode of administration, alternatives are sought where doses might be reduced and the bioavailability and efficacy enhanced. Local, controlled-release methods that deliver antibodies locally to site of disease, offer new possibilities with these potential advantages. However, protein drugs frequently exhibit formulation challenges when packaged in delivery vehicles, and as globular proteins, antibodies are no exception. Several examples of mAb controlled-release and local delivery strategies against several disease targets are reviewed. Importantly, several antibody delivery methods work in tandem with existing clinically-accepted therapeutics, sometimes exhibiting potentiating or synergistic effects in animal models with small molecule, systemically administered drugs.

Abstract
Anti-infective antibody-based immunotherapy has gained renewed interest since the crisis of antibiotic resistance and because there is no therapy against various viral infections. The immunoprophylaxis of respiratory infections aims to utilize the ability of local antibodies to neutralize inhaled micro-organisms and their cytopathic products. Immunoglobulins for intravenous use (i.v.i.g.) have a wide spectrum of specificities. Hyperimmune i.v.i.g. containing high titers of specific antibodies have demonstrated efficacy in clinical trials, notably against the respiratory syncytial virus. Monoclonal antibodies have the advantage to be homogenous and specific for one selected epitope and several studies have demonstrated their efficacy to neutralize several infectious agents. Moreover, antibodies can be administered topically and are effective at lower doses than those needed for systemic administration. The mechanism of action could be the agglutination of bacteria or viruses at the epithelial surfaces of the respiratory tract inhibiting the early steps of the infectious process. Thanks to new technologies of humanized monoclonal antibodies, immunotherapy offers real promising perspectives for prophylactic and therapeutic therapies against a variety of current or emerging infectious diseases.

Abstract
Bovine antibodies have recently attracted increasing attention, as they have been shown to exhibit prophylactic and therapeutic properties in selected infectious diseases in humans. In the present study, we have isolated bacterial artificial chromosomes and cosmid clones containing the bovine JH, mu, delta, gamma 1, gamma 2, gamma 3, epsilon, and alpha genes, which allowed us to make a contig of the genes within the bovine IGHC locus. The genes are arranged in a 5'-JH-7 kb-mu-5 kb-delta-33 kb-gamma 3-20 kb-gamma 1-34 kb-gamma 2-20 kb-epsilon- 13 kb-alpha-3' order, spanning approximately 150 kb DNA. Examination of the bovine germline JH locus revealed six JH segments, two of which, JH1 and JH2, were shown to be functional although there was a strong preference for expression of the former. Sequence alignment of the bovine 5' E mu enhancer core region with those of other mammals, demonstrated an absence of the mu E3 motif and a shortened spacer between the mu A and mu B sites within the bovine E mu enhancer core region. Furthermore, the essential sequence element for class switching, switch mu, spanning approximately 3-kb repetitive sequence and abundant in the switch region motifs CTGGG (187 repeats) and CTGAG (127 repeats), was identified immediately upstream of the mu gene. A further sequence comparison revealed that the bovine IGHC genes display an extensive polymorphism leading to expression of multiple antibody allotypes.

Abstract
Immunocompromised patients are at high risk of developing Candida infections. Although cell-mediated immunity is generally believed to play the main role in defence against fungi, antibodies could also be effective in immune defence by different mechanisms of action. The adherence capacity of four strains of Candida albicans to polystyrene and to some extracellular matrix components was investigated after incubation of the yeasts with non-specific and specific anti-C. albicans IgG. Experiments were carried out using a colorimetric method based upon the reduction of XTT tetrazolium (2,3-bis[2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide) by mitochondrially active blastospores in the presence of menadione. Incubation of the yeasts with IgG, specific or not, caused a decrease in the capacity for adherence to the surfaces studied. There was no significant effect of the specificity of the tested antibodies on the reduction of adherence capacity. In conclusion, total IgG could play a role in blocking the binding of C. albicans to host and medical device surfaces. These results suggest that regular survey of levels of total IgG in patients suffering from severe hypogammaglobulinaemia could be of interest for the prevention of systemic candidiasis.

Abstract
High dose intravenous immunoglobulins (IVIG) are important agents in the treatment of numerous diseases in rheumatology and dermatology. Because the diseases treated with IVIG are rare, their use is mostly not based on controlled randomized trials. Since the high costs of therapy often prohibit the use of IVIG as first line therapy and as there are no guidelines on the use of IVIG in dermatologic diseases, a consensus conference was held in Wiesbaden, Germany, to address these issues. This manuscript documents the expert consensus on the use of IVIG in dermatology and reflects current clinical practice. It should be a guideline for the practitioner for the use of IVIG in dermatologic diseases.

Abstract
Adjuvant high-dose intravenous immunoglobulins (IVIgs) are being used increasingly in a range of immune-mediated and autoimmune diseases. Although numerous immunomodulatory mechanisms have been suggested, the exact mechanisms of action are poorly understood. The efficacy of IVIg in certain diseases has been proven in clinical trials, insofar as IVIg is approved as the therapy of choice for Kawasaki syndrome or idiopathic thrombocytopenic purpura. IVIg treatment has been shown to be safe, without the many drug-related adverse effects, including systemic immunosuppression, that are related to corticosteroids and other immunosuppressive agents. Current dermatologic uses of IVIg are increasing, which calls for adequately controlled clinical trials. This review focuses on experiences with IVIg therapy for skin diseases and discusses current opinion concerning its potential immunomodulating mechanisms.

Abstract
The immunoglobulins of bovine colostrum provide the major antimicrobial protection against microbial infections and confer a passive immunity to the newborn calf until its own immune system matures. The concentration in colostrum of specific antibodies against pathogens can be raised by immunising cows with these pathogens or their antigens. Immune milk products are preparations made of such hyperimmune colostrum or antibodies enriched from it. These preparations can be used to give effective specific protection against different enteric diseases in calves and suckling pigs. Colostral immunoglobulin supplements designed for farm animals are commercially available in many countries. Also, some immune milk products containing specific antibodies against certain pathogens have been launched on the market. A number of clinical studies are currently in progress to evaluate the efficacy of immune milks in the prevention and treatment of various human infections, including those caused by antibiotic resistant bacteria. Bovine colostrum-based immune milk products have proven effective in prophylaxis against various infectious diseases in humans. Good results have been obtained with products targeted against rotavirus, Shigella flexneri, Escherichia coli, Clostridium difficile, Streptococcus mutans, Cryptosporidium parvum and Helicobacter pylori. Some successful attempts have been made to use immune milk in balancing gastrointestinal microbial flora. Immune milk products are promising examples of health-promoting functional foods, or nutraceuticals. This review summarises the recent progress in the development of these products and evaluates their potential as dietary supplements and in clinical nutrition.

Abstract
For more than a century, antibody has been used for passive parenteral immunization against viral and bacterial pathogens. This approach has been successful for prevention of viral respiratory infection and has led to testing of intranasal or aerosol delivery of antibody to passively immunize the respiratory tract mucosal surface. Mucosal delivery may be advantageous because it allows the antibody to neutralize the virus particles before they initiate infection and because it concentrates the antibody where viral replication takes place. Animal studies have shown the feasibility of passive intranasal immunization against a number of respiratory tract viruses. Development of nasal antibody treatments for humans is under way, and early clinical studies have confirmed that this approach is safe and can be used to prevent respiratory tract disease. Polyclonal human immunoglobulin from pooled plasma preparations can be used to provide broad protection against a number of different pathogens, while monoclonal antibodies or their fragments can be used to target specific viruses.

Abstract
BACKGROUND Oral ingestion of immunoglobulins in humans has been shown to be effective as prophylaxis against enteric infections. However, its therapeutic effect in children with infectious diarrhea has hitherto not been proven. We treated children with rotavirus diarrhea with immunoglobulins extracted from immunized bovine colostrum (IIBC) containing high titers of antibodies against four rotavirus serotypes. METHODS In this double blind placebo-controlled trial, 80 children with rotavirus diarrhea were randomly assigned to receive orally either 10 g of IIBC (containing 3.6 g of antirotavirus antibodies) daily for 4 days or the same amount of a placebo preparation. The daily stool output (grams/kg/day), intake of oral rehydration solution (ml/kg/day), stool frequency (number of stools/day) and presence of rotavirus in stool were monitored for the 4 days during treatment. RESULTS Children who received IIBC had significantly less daily and total stool output and stool frequency and required a smaller amount of oral rehydration solution than did children who received placebo (P < 0.05). Clearance of rotavirus from the stool was also earlier in the IIBC group compared with the placebo group (mean day, 1.5 vs. 2.9, P < 0.001). No adverse reactions from the colostrum treatment were observed. CONCLUSIONS Treatment with antirotavirus immunoglobulin of bovine colostral origin is effective in the management of children with acute rotavirus diarrhea.

Abstract
BACKGROUND Antibodies from hyperimmune bovine colostrum have been shown to be effective in treatment against a variety of microorganisms, including Helicobacter pylori in adults. AIM To test this form of treatment in a small group of H. pylori infected children in a periurban community in Bangladesh. METHODS Twenty-four infants, 4-29 months old (mean age 16.5+/-7.7 months) and infected with H. pylori, were treated with purified immunoglobulins from hyperimmune bovine colostrum for 1 month, in a placebo-controlled, double-blind pilot study. Diagnosis was established with 13C-urea breath test (UBT) before and after the treatment period and at a 1-month follow-up. RESULTS None of the hyperimmune bovine colostrum-treated children became UBT negative. Five children initially positive in the UBT screening spontaneously became negative by the start of the study with hyperimmune bovine colostrum/placebo. At the end of the 1-month study period, three had became positive again. CONCLUSION Hyperimmune bovine colostrum does not eradicate H. pylori infection in infants. Transient H. pylori infection is common among infants in high endemic areas, as is reinfection after clearance. This presents obstacles to evaluation of therapeutic investigations in young children in areas where H. pylori is prevalent.

Abstract
Patients with IgA deficiency often demonstrate circulating antibodies against IgA, which have been suggested to be associated with transfusion reactions. Sera from three patients with common variable immunodeficiency (CVID) and one with a selective IgA deficiency with anti-IgA antibodies receiving subcutaneous gammaglobulin replacement therapy were analysed for serum levels of IgG, IgA and anti-IgA before and during a treatment period of 4-7 years. Treatment with gammaglobulin preparations containing significant amounts of IgA (< 5 mg/ml) resulted in a decrease or disappearance of the anti-IgA antibodies. Analysis of serum fractions, however, revealed anti-IgA activity in the complex-containing fractions. In vitro experiments gave similar results with a shift of anti-IgA activity from the monomeric to the complex-containing fractions (that could not be detected in whole serum). When the patients were subsequently switched to treatment with a preparation containing less IgA (< 80 microg/ml) or made an interruption in the treatment schedule, the anti-IgA antibodies reappeared. Importantly, however, one of the patients lost his anti-IgA activity during a 3-month period on the preparation containing the higher IgA levels, and these antibodies did not reappear after switching to the low IgA-containing preparation. After 5 years on this preparation, anti-IgA can still not be detected, suggesting induction of unresponsiveness.

Abstract
Antibodies have been investigated as specific targeting agents for cancer diagnosis and therapy, to inactivate toxic substances including drugs and also as passive immunotherapy for neoplastic or infectious diseases. In most cases the antibodies were administered systemically by the intravenous route. More recently, however, there has been increasing interest in the oral administration of antibodies for localised treatment of infections or other conditions in the gastrointestinal tract. The normal physiological handling of ingested proteins is degradation by proteases in the stomach and intestine into small peptides or amino acids which are subsequently absorbed. Proteolytic enzymes involved in the degradation of orally administered immunoglobulins include pepsin, trypsin, chymotrypsin, carboxypeptidase and elastase. These enzymes initially degrade the antibodies to F(ab')2. Fab and Fc fragments. The F(ab')2 and Fab fragments, however, retain some of their neutralising activity locally in the gastrointestinal tract. Various approaches are possible to increase the stability of orally administered antibodies against proteolysis, including formulation in liposomes, coating with polymers and genetic engineering of resistant forms. The clinical application of orally administered antibodies includes the treatment and prevention of gastrointestinal infections caused by enteric pathogens such as rotavirus, Escherichia coli or Vibrio cholerae in susceptible individuals including those with immunodeficiency diseases and patients with bone marrow transplants. There is also a suggestion that such agents may be useful in preventing chemotherapy-induced gastrointestinal mucositis. Future opportunities for research include the design of oral dosage forms of antibodies which resist proteolysis and can deliver a greater fraction of immunoreactive antibody locally in the gastrointestinal tract for the treatment of infections or perhaps even to allow the absorption of antibodies for the treatment or prevention of systemic conditions.

Abstract
Passive immunity against a variety of respiratory and gastrointestinal pathogens has recently been increasingly used clinically, and oral administration of antibodies of both human and non-human origin has been tried both for prophylaxis and treatment of infections. Although the former type of therapy has been shown to be effective, data on the latter are still scarce. This commentary focuses on recent studies on successful oral therapeutic administration of bovine immunoglobulins.

Abstract
In two independent trials 10 and 12 healthy volunteers received the novel intravenous immunoglobulin (IVIG) preparations BT 511 and BT 507, respectively. BT 511 contains 5 g human plasma proteins per 100 ml, more than 95% of which are immunoglobulins of the G class (IgG). BT 507 contains in addition 61 IU antibody against hepatitis B surface antigen (anti-HBs).ml-1. In trial I volunteers received 4.0 ml/kg (n = 4) and 8.0 ml.kg-1 (n = 6) BT 511 to study the tolerability and the magnitude of the increase in immunoglobulins in plasma as well as their decline over 1 month. After administration of the lower dose, plasma IgG increased from 10.7 to 14.7 g.l-1 directly after the infusion. Following the 8.0 ml.kg-1 dose a more pronounced increase from 12.4 to 21.2 g.l-1 was observed. No adverse events occurred. After 1 month IgG concentrations had almost reached baseline values at 12.2 g.l-1 in the 4.0 ml.kg-1 group, but were still significantly increased at 15.2 g.l-1 after the high dose. There was a linear correlation between the maximal IgG plasma concentration and the subsequent decline of IgG during the 29-day observation period. After administration of BT 507 maximal anti-HBs concentrations of 1778 mU.ml-1 occurred 1.4 h after termination of the infusion. The terminal elimination half-life was 22.4 days, and total clearance and volume of distribution were determined to be 0.122 ml.min-1 and 5.41, respectively. The pharmacokinetic parameters calculated for anti-HBs as an indicator of IgG were in accordance with the pharmacokinetic behaviour of native IgG.
