N2 - Hepatocyte growth factor (HGF) is a member of the angiogenic growth factor family, which exerts a variety of effects on epithelial, endothelial, and neuronal cells by binding to the c-MET receptor tyrosine kinase. It was reported that HGF attenuates cerebral ischemia-induced increase in permeability of the blood-brain barrier (BBB) and decreases in expression of tight junction proteins in cerebral vessels of rats. Studies on the localization of the c-Met/HGF receptor in the rat brain and the interaction with HGF after brain injuries show that HGF plays an important role as a neurotrophic factor in the ...
The role of complement in innate, adaptive and eosinophil-dependent immunity to the nematode Nippostrongylus brasiliensis -...
Complement may be important for immunity to infection with parasitic helminths, by promoting the recruitment of leukocytes to infected tissues and by modulating the function of cytotoxic effector leukocytes. However, the importance of complement in vivo during helminth infection is poorly understood. In this study, mice lacking classical (C1q-deficient), alternative (factor B-deficient) or all pathways of complement activation (C3-deficient) were used to assess the role of complement in immunity to the nematode Nippostrongylus brasiliensis. Double-mutant complement-deficient/IL-5 transgenic (Tg) mice were used to determine if complement is required for the strong eosinophil-dependent resistance to this parasite. Complement activation on larvae (C3 deposition), extracellular eosinophil peroxidase activity, larval aggregation and eosinophil recruitment to the skin 30 min post-injection (p.i.) of larvae were reduced in factor B-deficient mice. Inhibition of the C5a receptor with the antagonist ...
The Role of CD4+ and CD8+ T-Cells during Angiostrongylus vasorum Infection in Dogs
A determinant factor in the pathology of canine angiostrongylosis seems to be related to the location of the parasite in the definitive host. Their presence inside the arteries and its branches, promoting mechanical and metabolic action on the wall of the vessels, may alter its homeostasis. Bronchoalveolar lavage (BAL) is a procedure that retrieves cells and other elements from de lungs for evaluation, and helps in the diagnosis of many pulmonary diseases. The aim of this study was to evaluate CD4+/CD8+ lymphocyte profile during the infection by Angiostrongylus vasorum, using cells retrieved using BAL. The identification of subpopulations of T lymphocytes by evaluating the co-expression of CD4 and CD8 receptor proteins has shown that despite the increase in both populations, there was a predominance of CD4+ T-cells, instead of CD8+ T-cells. These increases of CD4+ T-cells associated with the increase of the ratio between CD4+/CD8+ suggest polarization of a Th2 response. However, the immune cells,
Isolation of Nippostrongylus brasiliensis Larvae from Mouse Lungs -BIO-PROTOCOL
The rodent parasite Nippostrongylus brasiliensis (N. brasiliensis) models the salient features of helminth infection including skin penetration, migration from tissues to lung, maturation and egg production in the gut. As a potent activator of systemic and mucosal Th2 immune responses, Nippostrongylus brasiliensis has been extensively used to study host protective immunity and in vivo regulation of Th2 immune response. Six to eight week old C57Bl/6J, Balb/c mice or any other strains are suitable, as all are susceptible to infection. Inocula of 150-650 L3 larvae can be administered by subcutaneous injection, but for greatest consistency a dose of 550 L3 larvae is routinely used for experimental purposes. We have optimized three different protocols for the isolation of larvae from the lungs of mice infected with the L3 stage of Nippostrongylus brasiliensis. Larvae can migrate to the lung between 18-60 h post inoculation from any site in the body. The numbers of larvae appearing in the lung peaks at 48 h
A Case Report on Eosinophilic Meningitis Caused by Angiostrongylus cantonensis
The clinical stages of eosinophilic meningitis include a latent stage lasting 3 to 36 d (average 15 d), with no obvious clinical signs. The symptoms of the following prodromal stage are mild, and may include fever, headache, dizziness, abdominalgia, diarrhea and lack of strength. In some patients, the symptoms can resolve without any treatment. At the next, acute stage, patients have severe fever and headache with nausea, vomiting and abnormal sensations of the skin (e.g., numbness, pain, tingling, burning). Some patients have stiff neck, numbness of face or limbs, photophobia and diplopia. Symptoms at the acute stage may last from one week to 2 months or even longer. In the recovery stage, symptoms start to resolve and patients gradually regain normal status. Recovery can last for several weeks, depending on the individual. Some measurements (such as eosinophils counts, CSF pressure, positive head MRI signals and lung shadow) and mildly abnormal sensations could last longer.. Angiostrongyliasis ...

Mechanisms of neonatal mucosal antibody protection - Zurich Open Repository and Archive
Following an abrupt transition at birth from the sterile uterus to an environment with abundant commensal and pathogenic microbes, neonatal mammals are protected by maternal Abs at mucosal surfaces. We show in mice that different Ab isotypes work in distinct ways to protect the neonatal mucosal surface. Secretory IgA acts to limit penetration of commensal intestinal bacteria through the neonatal intestinal epithelium: an apparently primitive process that does not require diversification of the primary natural Ab repertoire. In contrast, neonatal protection against the exclusively luminal parasite Heligmosomoides polygyrus required IgG from primed females. This immune IgG could either be delivered directly in milk or retrotransported via neonatal Fc receptor from the neonatal serum into the intestinal lumen to exert its protective effect. ...

Publications | Sharpe Laboratory
B7-1/B7-2 interactions are required for many Th2-cell mediated primary immune responses including the response that follows infection with the intestinal nematode parasite, Heligmosomoides polygyrus. However, few studies have examined the role of B7-1/B7-2/CD28 interactions in the development of a Th2 memory immune response. We examined the development of the memory Th2 response to H. polygyrus in BALB/c mice deficient in both B7-1 and B7-2 (B7-1/B7-2(-/-)) and in BALB/c mice deficient in CD28 (CD28(-/-)). Following primary inoculation with H. polygyrus, adult worms in the gut were cleared with an anti-helminthic drug and mice were subsequently challenge-inoculated with H. polygyrus larvae. The memory Th2 response is readily distinguished by its inhibitory effect on adult worm maturation, resulting in marked reductions in adult worm egg production that are not observed during the primary immune response. Following H. polygyrus challenge inoculation, comparable decreases in egg production and ...
New Childrens Book - The Mystery of Rat Lungworm Disease | Hawaii News and Island Information
A University of Hawaiʻi at Hilo College of Pharmacy researcher has developed a fun-filled activity book to teach children about a serious health topic associated with cleaning and cooking vegetables in the tropical Hawaiian environment.. Dr. Susan Jarvi, associate professor in the Department of Pharmaceutical Sciences, is distributing a book and poster about Rat Lungworm Disease (Angiostrongylus cantonensis) to elementary school children in Hilo. But she wants everyone in Hawaiʻi to know more about the rare parasitic infection that can cause paralysis, coma or death.. Theres a real need for better education of the public and research that no one else is doing if we want to decrease risk of infection, said Jarvi, who has been conducting research on ways to detect the virus in the blood as well as testing possible vaccines and evaluating vegetable washes that may be the most effective in killing the A. cantonensis larvae that causes the damage..

Retnla (Relmα/Fizz1) Suppresses Helminth-Induced Th2-Type Immunity
Author Summary Retnla is a member of a family of cysteine-rich secreted proteins, referred to as resistin-like molecules or found in inflammatory zone that increase in expression during allergic reactions and following infection with a variety of metazoan parasites. Retnla was originally hypothesized to function as an effector molecule during helminth-induced Th2-type immune responses. Studies conducted here with Retnla-deficient mice, however, suggest that Retnla primarily functions as a regulatory molecule during helminth infection. Using three helminth model systems affecting three different organ systems, we show that Retlna is induced by IL-4 and IL-13 as a mechanism to suppress Th2-type immunity. Retnla deficiency increased inflammation in the lung following i.v. challenge with Schistosoma mansoni eggs. Retnla deficiency also accelerated the development of liver fibrosis following S. mansoni infection. This finding was particularly surprising since Retnla was previously shown to activate
Parasite sickens Thai workers after they eat raw snails - Taipei Times
Four out of five Thai workers who ate raw snails earlier in the month became infected with a potentially deadly parasite, the Department of Health (DOH) said on Wednesday.
Centers for Disease Control Deputy Director Chou Jih-haw (周志浩) said that three of the workers were in stable condition, while one had left Taiwan and the other had not shown any symptoms of illness.
Three of the workers were reported to have been infected with the parasitic nematode Angiostrongylus cantonensis - an elongated cylindrical worm - early this month and developed symptoms of eosinophilic meningitis, including headaches, fever and vomiting, Chou said.

BHLHE40 Promotes TH2 Cell-Mediated Antihelminth Immunity and Reveals Cooperative CSF2RB Family Cytokines | The Journal of...
The transcription factor BHLHE40 is an emerging regulator of the immune system. Recent studies suggest that BHLHE40 regulates type 2 immunity, but this has not been demonstrated in vivo. We found that BHLHE40 is required in T cells for a protective TH2 cell response in mice infected with the helminth Heligmosomoides polygyrus bakeri. H. polygyrus elicited changes in gene and cytokine expression by lamina propria CD4+ T cells, many of which were BHLHE40 dependent, including production of the common β (CSF2RB) chain family cytokines GM-CSF and IL-5. In contrast to deficiency in GM-CSF or IL-5 alone, loss of both GM-CSF and IL-5 signaling impaired protection against H. polygyrus. Overall, we show that BHLHE40 regulates the TH2 cell transcriptional program during helminth infection to support normal expression of Csf2, Il5, and other genes required for protection and reveal unexpected redundancy of common β chain-dependent cytokines previously thought to possess substantially divergent functions. ...

Helminth Infections Decrease Host Susceptibility to Immune-Mediated Diseases | The Journal of Immunology
Animal models of IBD suggest that Tregs help to prevent excessive intestinal inflammation (4). The murine gut harbors large numbers of Foxp3+CD4+ Tregs. The colon and terminal ileum contain most of the intestinal flora. In the distal bowel, ∼25% of the lamina propria CD4+ T cells express Foxp3, and the Foxp3+ T cells are the major source of IL-10 (5). These cells likely function to restrain the host immune response to the normal intestinal flora.. Heligmosomoides polygyrus bakeri is a luminal murine helminth that lives in the proximal small bowel, with only the larval stages superficially invading the epithelial lining. This parasite expands the number of Foxp3+ T cells in the mesenteric lymph nodes (MLNs) (6, 7) and intestinal lamina propria of its murine host (5). The costimulatory receptor ICOS facilitates this Treg expansion (8). This helminth also activates Tregs, making them highly regulatory (5). Rag mice reconstituted with CD25−CD4+ T cells develop intestinal inflammation as a ...
Geographical, clinical, clinicopathological and radiographic features of canine angiostrongylosis in Irish dogs: a...
The present study illustrates that infection with A. vasorum remains endemic in Ireland, is not confined to the East Coast, can occur in any age of dog and has a widely varying clinical picture.. In the present study, approximately 90% of affected animals either directly referred or from external post mortem or faecal submissions were from the East Coast of Ireland. These results may imply an endemic focus in this area. However, the two major counties represented are within the referral catchment area for the UCD Veterinary Hospital, likely creating a degree of bias. Only five animals were from beyond this area with two from the West of Ireland. The only other published report of dogs affected in the West of Ireland was documented decades ago [6]. This may truly reflect a low prevalence beyond the East Coast. However, it could also reflect limited referral of cases from this geographic location or a failure to consider the differential because of a perception that angiostrongylosis does not ...

Foxp3-expressing regulatory T (T reg) cells have been implicated in parasite-driven inhibition of host immunity during chronic infection. We addressed whether parasites can directly induce T reg cells. Foxp3 expression was stimulated in naive Foxp3 − T cells in mice infected with the intestinal helminth Heligmosomoides polygyrus . In vitro, parasite-secreted proteins (termed H. polygyrus excretory-secretory antigen [HES]) induced de novo Foxp3 expression in fluorescence-sorted Foxp3 − splenocytes from Foxp3-green fluorescent protein reporter mice. HES-induced T reg cells suppressed both in vitro effector cell proliferation and in vivo allergic airway inflammation. HES ligated the transforming growth factor (TGF) β receptor and promoted Smad2/3 phosphorylation. Foxp3 induction by HES was lost in dominant-negative TGF-βRII cells and was abolished by the TGF-β signaling inhibitor SB431542. This inhibitor also reduced worm burdens in H. polygyrus -infected mice. HES induced IL-17 in the ...

Group 2 innate lymphoid cells (ILC2s) release interleukin-13 (IL-13) during protective immunity to helminth infection and detrimentally during allergy and asthma. Using two mouse models to deplete ILC2s invivo, we demonstrate that T helper 2 (Th2) cell responses are impaired in the absence of ILC2s. We show that MHCII-expressing ILC2s interact with antigen-specific Tcells to instigate a dialog in which IL-2 production from Tcells promotes ILC2 proliferation and IL-13 production. Deletion of MHCII renders IL-13-expressing ILC2s incapable of efficiently inducing Nippostrongylus brasiliensis expulsion. Thus, during transition to adaptive Tcell-mediated immunity, the ILC2 and Tcell crosstalk contributes to their mutual maintenance, expansion and cytokine production. This interaction appears to augment dendritic-cell-induced Tcell activation and identifies a previously unappreciated pathway in the regulation of type-2 immunity. © 2014 The Authors.

Clinical and epidemiological aspects of abdominal angiostrongyliasis in Southern Brazil
SUMMARY Most of the cases of abdominal angiostrongyliasis in Brazil were reported from the southern States of São Paulo, Paraná, Santa Catarina and Rio Grande do Sul (RS). A study in 27 cases from RS revealed a distinct local epidemiology. Peasants were usually affected, either adults or children, from the mountainous areas in the north of the Suite. There was a seasonal increase in the number of cases, from late spring to autumn, that does not coincide with the rainy season. Besides the most common clinical features of abdominal pain, fever and cosinophilia in the leucogram, painful relapsing episodes were detected in some patients. The abdominal pain could be either localized or diffuse during the rapid evolution to a surgical abdominal condition, with a letality of 7.4%. The use of a serological test and the greater awareness of physicians working in endemic areas is expected to improve the recognition of uncomplicated and benign courses of the disease. This study confirms the known ...
An Interesting Case of Eosinophilic Meningitis - MAHE Digital Repository
Angiostrongylus cantonensis is one of the causative agents of eosinophilic meningitis. Humans get infected when they ingest raw or partially cooked snails or monitor lizards (Varanus bengalensis). There is a popular belief that the tongue and the liver of the monitor lizard has aphrodisiac properties. A 20-year-old man was admitted to our hospital with a history of fever, headache and vomiting. His cerebrospinal fluid revealed eosinophilia. He gave a history of the ingestion of a monitor lizard, ten days prior to the onset of the symptoms. So, a diagnosis of eosinophilic meningitis due to Angiostrongylus cantonensis was made. He was treated with oral albendazole and prednisolone. His symptoms improved gradually within two weeks from his admission.. ...

Angiostrongylus costaricensis - Wikipedia
Angiostrongylus costaricensis is a species of parasitic nematode. Its distribution includes Brazil. Humans and rodents are the definitive hosts. The main rodent host is the Cotton Rat. Molluscs are the intermediate host and are infected through ingestion or penetration of the foot by L1 infective larvae from infected feces. Limax maximus Slugs from the family Veronicellidae[citation needed] Pathology is due to both the adults and the eggs. Adults in the ileo-caecal arterioles cause an inflammatory (eosinophilic) response in humans. In the Cotton Rat the adult worms cause local haemorrhages. The intestinal wall is also affected. In humans there is a thickening of the intestinal wall (ileum, appendix and caecum). In rats with heavy infestations there is a yellow discolouring of the surface of the intestinal walls. Abdominal pain which presents as a palpable mass on clinical examination Anorexia Diarrhoea Vomiting In the blood and tissue biopsy there is eosinophilia. Other methods of diagnosis from ...
ANGIOSTRONGYLUS COSTARICENSIS PDF
Diagnosis Angiostrongylus cantonensis A diagnosis of A. History of ingestion of raw or undercooked intermediate hosts or possibly transport hosts is a crucial clue as well. However, ill persons may not be aware of ingestion of foods that could lead to infection. It is important to note, however, that eosinophilia in the CSF and in the blood may not be present on initial presentation or in late stages of infection. The CSF pressure is generally elevated. Recovery of A. Serologic tests have been developed but are not commercially available.. A few specialty or research laboratories offer serologic tests, but the sensitivity and specificity of the tests may not be optimal and the infection is often identified only on convalescent sera. Because of the difficulty in making the diagnosis, it is important to rule-out other causes of eosinophilic meningitis. Neuroimaging studies can be useful as there usually is an absence of focal lesions on CT scan, which helps to distinguish A.. Because eggs are not ...
PLOS Neglected Tropical Diseases: Invasive Snails and an Emerging Infectious Disease: Results from the First National Survey on...
Author Summary Eosinophilic meningitis is caused by the rat lungworm (Angiostrongylus cantonensis). This parasite is endemic in Southeast Asia, Australia, the Caribbean, and on Pacific Islands. Moreover, the disease is emerging in mainland China, which might be related to the spread of two invasive snail species (Achatina fulica and Pomacea canaliculata). Thus far, the biggest angiostrongyliasis outbreak in China occurred in 2006 in Beijing, involving 160 patients. However, detailed information about the national distribution of A. cantonensis and its intermediate hosts is still lacking, and the importance of the two invasive snail species for disease transmission is not well understood. Therefore, a national survey on the distribution of A. cantonensis and its intermediate hosts in China was carried out in 2006/2007. It was found that A. fulica and P. canaliculata were implicated in most angiostrongyliasis outbreaks, and that the distribution of A. cantonensis closely matched that of these snails. The

Abstract
One hundred and twenty-five patients with eosinophilic meningitis or meningoencephalitis were studied in southern Taiwan in 1968 and 1969. The majority of patients had mild to moderate disease, but several had severe manifestations. Four patients died and three others had severe permanent sequelae such as blindness. Young adult Angiostrongylus cantonensis were recovered from nine patients, at autopsy in one, and from the cerebrospinal fluid of eight who survived. The clinical manifestations of cases of proven etiology were similar to those of cases from which parasites were not recovered and it is believed that the latter also were the result of infection with A. cantonensis.
What Is Eosinophilic Meningitis;What Does It Do? - Notes Read
Eosinophilic meningitis, a syndrome caused by Angiostrongylus cantonensis (the rat lung worm), was first recognized in New Caledonia in 1950, and has since been reported from Hawaii, Tahiti, other Pacific Islands, Indonesia, and Thailand. The human disease has only been reported from the Far East and the Pacific to date, although infected rats have been found in Madagascar, Mauritius, Ceylon, and Sarawak.. The life cycle was described by workers in Australia in 1955 before the importance of the worm as a human pathogen was known. A delicate filiform nematode, 17 to 25 mm. in length, the adult lives in the lungs of rats, and the eggs are coughed up, swallowed, and pass out in the feces as first-stage larvae. Further development occurs in slugs and snails to the third-stage infective larvae. These larvae are ingested by man either while in this intermediate host or after they have been shed by it onto some other article of food, e.g., lettuce.. Crabs and freshwater prawns have also been found to ...
Interleukin-13 Receptor α1-Dependent Responses in the Intestine Are Critical to Parasite Clearance. - Semantic Scholar
Nematode infection upregulates interleukin-4 (IL-4) and IL-13 and induces STAT6-dependent changes in gut function that promote worm clearance. IL-4 and IL-13 activate the type 2 IL-4 receptor (IL-4R), which contains the IL-13Rα1 and IL-4Rα chains. We used mice deficient in IL-13Rα1 (IL-13Rα1(-/-)) to examine the contribution of IL-13 acting at the type 2 IL-4R to immune and functional responses to primary (Hb1) and secondary (Hb2) infections with the gastrointestinal nematode parasite Heligmosomoides bakeri There were differences between strains in the IL-4 and IL-13 expression responses to Hb1 but not Hb2 infection. Following Hb2 infection, deficient mice had impaired worm expulsion and higher worm fecundity despite normal production of Th2-derived cytokines. The upregulation of IL-25 and IL-13Rα2 in Hb1- and Hb2-infected wild-type (WT) mice was absent in IL-13Rα1(-/-)mice. Goblet cell numbers and resistin-like molecule beta (RELM-β) expression were attenuated significantly in IL-13Rα1(-/-)mice

Dog lungworm, SEM - Stock Video Clip K006/9270 - Science Photo Library
Animated coloured scanning electron micrograph (SEM) of a dog lungworm (Angiostrongylus vasorum) Also known as the French heartworm, this is a common filarial nematode parasite of dogs and rarely humans. The adult worms are large, measuring up to 25 centimetres long, and they typically live in the dogs right heart and pulmonary artery. It causes the disease canine angiostrongylosis in dogs. Female worms produce microfilariae that are found in the dogs blood and can be ingested by mosquitoes. The microfilariae mature into infective juveniles in the mosquito and the infection is transmitted to a new host when the mosquito feeds such as dogs and humans. The natural intermediate hosts of Angiostrongylus vasorum are land slugs, land snails and freshwater snails. - Stock Video Clip K006/9270

Intestinal nematode parasites: mechanisms of resistance | British Society for Immunology
Intestinal nematode parasites are very common infections of man and his domestic animals. When the host becomes infected, often by oral ingestion of infective eggs, the parasite establishes in its intestinal niche. Parasite antigens are carried by intestinal dendritic cells, or drain freely in the lymph, to the local draining lymph node, the mesenteric lymph node. In the
Preventing rat lungworm disease | News, Sports, Jobs - Maui News
So far, the state Department of Health confirms six people infected by rat lungworm, with three cases still under investigation.. The disease stems from a parasitic worm, Angiostrongylus cantonensis, the adult form of which is only found in rodents. Infected rats pass the larvae in their feces, which are then ingested by snails, slugs and other mollusks.. We humans can then be infected by eating these snails or slugs, most often while they are hidden in produce. But really you can be infected by ingesting anything that has been tainted by the slime trail of the slugs or snails, including drinking water or eating freshwater animals such as prawns, frogs or crabs.. Most recently some individuals on Hawaii Island contracted the disease after drinking homemade kava, a ceremonial beverage that was left out in uncovered buckets. After consuming the kava, it was noticed that there was a slug at the bottom of the ceremonial bowl; the individuals became ill a few weeks later with two confirmed cases of ...

How to Know if a Snail Has the Rat Lungworm
Rat lungworm, or Angiostrongyliasis, is a parasitic worm found in the pulmonary arteries of rats. When the rat passes its faeces, the waste is sometimes eaten by small snails and other mollusks. The parasite is then passed on to the snail. Humans can contract the parasite from ingesting these snails.
Rat lungworm disease: Hawaii visitor eats slug, gets parasite | Columbus Ledger-Enquirer
Hawaii health officials confirmed 3 cases of rat lungworm disease, including one mainland US visitor infected with the parasite by eating a slug on a dare. That makes 10 angiostrongyliasis cases in 2018, 5 in 2019.
Hawaii teachers tackle a slimy subject: rat lungworm disease | Honolulu Star-Advertiser
Today Howe is doing all she can to educate people and stop the spread of the disease, formally known as angiostrongyliasis. On Tuesday she debuted the new curriculum she developed, Engaging Students in Citizen Science Through the Prevention of Rat Lungworm Disease.. The daylong professional development workshop for teachers was funded by the Department of Health, Iolani School, Oahu Farm to School Network and Hawaii Farm to School Hui. A longer course is anticipated for teachers on the Big Island this fall.. The workshop filled up quickly with 32 participants with more having to be turned away, according to Debbie Millikan, sustainability specialist at Iolani School and a presenter at the session. Participants came from all over, including Waialua High & Intermediate School, Hauula Elementary School and Kualapuu School on Molokai, as well as Iolani School, St. Andrews Priory and Le Jardin Academy.. Linda Higashi, a fifth-grade teacher at Kalihi Elementary, said she is eager to help her ...
Life of a Lab Rat: Studying Streptococcus - SGM series
One of my colleagues did her honours (kind of like a one year practice PhD, I dont know if its done anywhere outside of Australia) looking at Nippostrongylus brasiliensis infection in mice. Apparently you can find them in the lung but nobody could work out how the worm got from the site of infection to the lung. Anywho, they used whole animal bioluminescent imaging to track the worms throughout infection. They were trying to do it in both real-time for the acute infection and by compiled photos to map the migration over longer time frames. I dont think it worked very well but its fascinating technology. ...

Sustained IL-4 signaling throughout the reactive lymph node « Karine SERRE, PhD
A stimulating paper from Mohrs and colleagues that shows that IL-4 and IFN-g signaling during Heligmosomoides polygyrus or Toxoplasma gondii respectively, is: i) widespread throughout the LN, ii) independent of direct cell contact and, iii) is not a limiting factor in B cell maturation or helper T cell differentiation. These results are challenging in view of our own data that show that during LN responses to alum-precipitated protein antigens IL-4 is dispensable for the early induction, but not for the maintenance, of Th2-features including B cell maturation or helper T cell differentiation more. In addition, previous work from our laboratory has shown that Th1 and Th2 characteristics start to develop during T cell priming to alum-precipitated protein mixed with killed Bordetella pertussis. This suggests that cytokines in these circumstances do not act globally in the LN, and that Th2 response to hapten-protein can proceed in a node where there is substantial Th1 activity ...

Summer 2014 Small Animal News | Ashwood Veterinary Centre, Mohill, Co. Leitrim
It is time to get out and about and enjoy the Summer sunshine, but watch out for some dangers lurking about. Out in the garden be aware that slug pellets, bone meal and weedkillers are common sources of poisoning in dogs and cats. Also try to ensure that pets dont dig up spring bulbs and eat them since many are poisonous. If you have cats, be aware that nearly all types of lilies are highly toxic to cats. Even a small bit of pollen can cause sudden onset kidney failure in cats. Seek immediate veterinary advise if any case of poisoning is suspected. For a comprehensive list of common poisons check out http://www.dogstrust.ie/az/factsheetsanddownloads/poisonousplants11.pdf It is quite frightening how many common items around the house are poisonous to our pets. Slugs and snails love warmer wet weather and can cause trouble to dogs that enjoy playing with these creatures. Slugs and snails can carry the larvae of the life threatening lungworm parasite Angiostrongylus vasorum. Dogs can be infected ...

JCI - Helminth-induced arginase-1 exacerbates lung inflammation and disease severity in tuberculosis
enhanced arginase-1 activity was associated with increased lung inflammation. Moreover, in patients with pulmonary TB, lung damage correlated with increased serum activity of arginase-1, which was elevated in TB patients coinfected with helminths. Together, our data indicate that helminth coinfection induces arginase-1-expressing type 2 granulomas, thereby increasing inflammation and TB disease severity. These results also provide insight into the mechanisms by which helminth coinfections drive increased susceptibility, disease progression, and severity in TB.. ...
