Taconic Biosciences ajoute un nouveau modèle de système immunitaire humanisé (SIH) à son portefeuille de recherche en immuno-oncologie

Le nouveau modèle huNOG-EXL EA étend considérablement les fenêtres d’étude

RENSSELAER, N.Y., 22 janv. 2022 (GLOBE NEWSWIRE) — Taconic Biosciences, un leader mondial dans la fourniture de solutions de modèles animaux pour la découverte de médicaments, annonce le lancement de la souris à système immunitaire humanisé (SIH) huNOG-EXL EA (Early Access). Ce produit étend le portefeuille largement utilisé de Taconic. huNOG-EXL EA prolonge considérablement la fenêtre d’étude au cours de laquelle un modèle de souris à SIH avec lignée myéloïde peut être utilisée avec succès.

Les modèles huNOG-EXL de Taconic prennent en charge les cellules myéloïdes et lymphoïdes humaines, ce qui rend ces souris particulièrement utiles pour la recherche en immuno-oncologie et d’autres applications immunitaires. Avec l’allongement de la durée de vie de tout modèle à SIH soutenant les cellules myéloides, le modèle huNOG-EXL original (désormais appelé huNOG-EXL SA, ou Standard Access) est appliqué avec succès dans la recherche préclinique sur la découverte de médicaments depuis 2016. Le modèle huNOG-EXL SA est fourni après une étape de contrôle qualité à 10 semaines après la greffe. Les commentaires des utilisateurs suggèrent que les applications de recherche nécessitant des délais d’étude particulièrement longs ou une importation dans des régions avec de longues périodes de quarantaine présentent des obstacles expérimentaux et logistiques qui peuvent limiter l’utilité du modèle Standard Access (SA).

Le nouveau modèle huNOG-EXL EA supprime ces difficultés en donnant accès aux souris dotées du modèle huNOG-EXL peu après la greffe, ce qui étend la fenêtre d’étude utile. Cela rend l’huNOG-EXL EA idéal pour la greffe de tumeurs à croissance lente, pour des paradigmes de traitement plus longs ou diverses personnalisations d’étude. Un accès précoce à un modèle de lignée myéloïde étendue est également avantageux pour les chercheurs confrontés à des quarantaines d’importation de modèles, qui autrement consommeraient une part significative de la fenêtre d’étude utile pour ces souris. Comme le modèle huNOG-EXL EA est expédié avant qu’une étape de contrôle qualité de la greffe ne soit possible, il est fabriqué à l’aide de cellules de donateurs précédemment validées pour bien greffer afin de réduire le risque de défaillances de greffe.

« Le modèle huNOG-EXL EA répond aux besoins scientifiques critiques des chercheurs qui mènent des recherches en immuno-oncologie ou étudient d’autres maladies immunitaires », a déclaré le Dr Michael Seiler, vice-président des produits commerciaux chez Taconic. « Après avoir mené une recherche et un développement approfondis, ainsi que des tests bêta rigoureux avec plusieurs partenaires de l’industrie, Taconic est ravie d’offrir désormais le nouveau modèle et d’étendre l’utilité de cette souris humanisée unique. »

Cameroon Hosts Influx of Football Fans from Neighboring Gabon, Equatorial Guinea

YAOUNDÉ, CAMEROON — Cameroon says that within four days, at least 1,500 football supporters have entered the country from neighboring Equatorial Guinea and Gabon to support their teams that have advanced to Round 16 in the Africa Football Cup of Nations, or AFCON. Gabon battles Burkina Faso Sunday, while Equatorial Guinea plays against Mali Wednesday. Tournament organizers require all fans to have COVID-19 tests before entering stadiums.]

Cameroon’s immigration police said Saturday that buses carrying at least 900 football fans from Gabon and Equatorial Guinea have entered the central African state within 48 hours. Gabon and Equatorial Guinea are Cameroon’s southern neighbors.

The immigration police said about 600 other football fans from Gabon and Equatorial Guinea arrived in Cameroon by sea and by air this week.

Cameroon says the influx came after Gabon and Equatorial Guinea qualified for the knockout stage of the Africa Football Cup of Nations, or AFCON, in Cameroon. Gabon played a 2-2 draw Tuesday against Morocco in Yaoundé, and both teams advanced.


Equatorial Guinea sealed their place after a 1-0 win against Sierra Leone in a group match played at Limbes Omnisport Stadium in Cameroon’s English-speaking South West region Thursday.

Thirty-year-old Prosper Ebang is among the 1,500 supporters from Gabon and Equatorial Guinea Cameroon police say have entered Cameroon. Ebang says he wants to be part of a continental soccer event in which his country’s national football team, the Panthers of Gabon, are doing well.

Ebang says no citizen who loves Gabon can be indifferent when the Panthers are making Gabon proud with the excellent football exhibited in Cameroon during AFCON. He says he is certain that Gabon will reach the AFCON final if Cameroon continues providing a conducive environment for the games.

Felix Nguele Nguele is the governor of Cameroon’s South region that borders Gabon and Equatorial Guinea. He says Gabon and Equatorial Guinea officials have informed him that hundreds of other supporters are still on their way to Cameroon.

Ngueles says he has asked police and military in Cameroon’s southern border to ensure the safety of football fans and supporters from Gabon and Equatorial Guinea. He says he knows that people with evil intentions may want to disturb the visiting supporters since tensions mounted between Cameroon and Equatorial Guinea in November.

On November 30, 2021, Cameroon said Equatorial Guinea was deporting thousands of Cameroonians who were living in the neighboring state illegally, citing national security concerns. Authorities in the capital, Malabo, said the Cameroonians fled conflict in western Cameroon, where government troops have been fighting anglophone separatists.

Videos from Cameroonians deported from Equatorial Guinea flooded social media platforms including Facebook and WhatsApp. In the video, Cameroonians claiming to have been forcibly sent out of Equatorial Guinea promised to chase football fans from the neighboring country visiting Cameroon for AFCON from January 9 to February 6.

Kisito Esua is president of the nongovernmental organization South West Youth League, headquartered in Limbe, an English-speaking southwestern town. Esua says the league is teaching youths to be hospitable to fans coming to Cameroon to support their football teams. He spoke via a messaging app from Limbe.

“The influx of fans and supporters from Gabon and Equatorial Guinea is so massive,” said Esua. “The fans have been coming in in their numbers by air, land and sea and we think that the turnout tomorrow will be something spectacular. So, we have made sure that the environment is so friendly, convivial and conducive.”

Cameroon’s Public Health ministry says the supporters who have arrived within the past 48 hours must respect COVID-19 restriction guidelines imposed by the Confederation of African Football. CAF says people must provide negative COVID-19 test results that are not more than 24 hours old as well as proof they have been vaccinated against COVID-19 to gain access to stadiums for AFCON matches.

The embassies of Gabon and Equatorial Guinea in Yaoundé say all the visiting fans have agreed to respect Cameroonian laws and COVID-19 restrictions instituted by Cameroon and CAF during their stay.

Egypt Announces New Travel Restrictions Amid COVID-19 Spread

The spread of COVID-19 has prompted the Egyptian Health Ministry to tighten up health restrictions at airports, seaports and land crossings.

 

Starting today, “Egyptian and foreign travellers to Egypt, except children below the age of 12, will be required to present certificates of coronavirus vaccination, or negative results of coronavirus tests,” the ministry said in a statement, on Thursday.

 

A traveller has to bring a certification of having received a single-dose or two-dose vaccine, at least 14 days before arrival, or the result of a test taken within 72 hours prior to the arrival, the statement said.

 

Egypt witnessed a recent surge in daily infections, with 1,403 new cases and 22 more deaths recorded nationwide by Thursday, pushing up the respective total to 405,393 and 22,260.

Burkina Faso authorities ban planned Saturday Ouagadougou protests

Authorities in Burkina Faso’s capital, Ouagadougou, have banned an anti-government protest planned for Saturday, two months after another rally turned violent.

 

The demonstration, called by a civil society movement called Sauvons le Burkina (Save Burkina), was prohibited for “security reasons”, Christian Charles Rouamba, municipal secretary, said in a letter on Thursday.

 

The same group had staged another banned protest in late November 2021 against the failure of President Roch Marc Christian Kabore’s government to stop attacks by armed groups affiliated with Daesh and al-Qaeda. Hundreds of demonstrators defied the ban to take to Ouagadougou’s streets on Nov 27 and about a dozen people were injured in clashes with security forces.

 

A separate demonstration also planned for Saturday in support of neighboring Mali, whose military government is under sanctions imposed by the regional bloc the Economic Community of African States, was also banned.

 

Two officials of the Coalition of African Patriots-Burkina Faso, which had called the rally, were arrested on Thursday, the group said.

 

Burkina Faso’s government has come under sustained pressure over failures to stem the bloodshed of the brutal six-year conflict which has killed some 2, 000 people, forced 1.4 million from their homes and spawned an immense humanitarian crisis.

 

The worsening security situation has led to street protests calling for Kabore to step down.

 

Following waves of protests, Kabore last month replaced the entire government and named Lassina Zerbo as the country’s new prime minister, the latest upheaval in a leadership shake-up that has included military top brass and heads of intelligence agencies.

 

Earlier in January, Burkinabe authorities arrested eight soldiers, including a high-ranking commander, in connection with an alleged plot to “destabilize” the country’s institutions.

Nigeria outrage at Kano schoolgirl Hanifa Abubakar killing

The discovery of the decomposing body of five-year-old schoolgirl Hanifa Abubakar has triggered shock and outrage across Nigeria, where the hashtag #JusticeForHanifa is trending.

 

The owner of her school, Abdulmalik Mohammed Tanko, has been arrested and the establishment closed.

 

He allegedly kidnapped Hanifa in the northern Kano state in December to demand a ransom of $14,600.

 

Police say he later killed Hanifa after realising she had recognised him.

 

According to the authorities, Tanko, 34, led officers to the school premises where he had buried the schoolgirl’s body in a shallow grave.

 

Her remains were then exhumed for medical examination and a proper burial by her family.

 

Tanko has not yet been charged.

 

Hanifa was allegedly abducted in early December outside an Islamic school that she also attended.

 

Two other suspects have been arrested, police say.

 

Kano state commissioner of education Sanusi Sai’du Kiru described the kidnapping as a betrayal of trust.

 

Nigeria is grappling with a wave of kidnappings for ransom, mostly by armed gangs who frequently target schools for mass abductions of students but the kidnapping of students by school officials is extremely rare.
