A new study on mice, published in the open access journal PLOS Biology discovered a connection between
the genes that contribute to hair colour and the genes that notify our bodies of a pathogenic infection.

According to the researchers, when a body is under attack from a virus or bacteria, the innate immune
the system detects them and responds by producing signalling molecules called interferons.

Interferons signal to other cells to take action by turning on the expression of genes that inhibit viral
replication, activate immune effector cells, and increase host defences.

Melissa Harris, the lead author and assistant professor within the Department of Biology at UAB found a
connection between hair pigmentation and innate immune regulation.

In this study, an unexpected link was found between gray hair, the transcription factor MITF or Melanogenesis
Associated Transcription Factor, and innate immunity.

MITF is best known for its role in regulating the many functions within melanocytes.

The researchers found that MITF also serves to keep the melanocytes’ interferon response in check.

Harris said melanocyte stem cells were essential to hair colour as they produced the melanocytes that were responsible for making and depositing pigment into the hair shaft.

They found that if MITF’s control of the interferon response was lost in melanocyte stem cells, hair-graying resulted.

Furthermore, if innate immune signaling is artificially activated in mice that are predisposed for getting gray
hair, increased numbers of gray hairs are also produced.

“This new discovery suggests that genes that control pigment in hair and skin also work to control the innate immune system,” said William Pavan, study co-author and chief of the Genetic Disease Research Branch at National Human Genome Research Institute under National Institute of Health.

“These results may enhance our understanding of hair graying. More importantly, discovering this connection
will help us understand pigmentation diseases with innate immune system involvement like vitiligo,”
said Paven.

Buhari: 12 million Nigerian children are afraid of attending school

post-image

According to President Buhari, 12 million children in the country have been traumatized and are frightened to attend  school because of the high prevalence of kidnapping.

On Tuesday, October 26, the President announced this during the launch of the Safe School Programme in Abuja.

The President, who was represented at the ceremony by his Chief of Staff, Prof. Ibrahim Gambari, also stated that dealing with security concerns in the country has been difficult.

“The incessant attacks on the country’s education system such as kidnapping, abduction of pupils/students, increased activities of insurgence and general insecurity in our schools have exacerbated many factors responsible for the growing number of out-of-school children.

It is disheartening to note that even when the abducted students are released, the trauma of the incidences remains long in their minds; hence the plan to have teachers trained on psycho-social support.

There are more than 12 million children currently traumatised and afraid of…

APC: Nigerians still trust us, we will win 2023 elections convincingly

post-image

Nigeria’s ruling party, the All Progressives Congress (APC), claims it would “convincingly” win the next gubernatorial election in Anambra and the presidential election in 2023.

John Akpanudoedehe, national secretary of the APC caretaker committee, said on Thursday, October 21 at the inauguration of the state congress appeal committee in Abuja that all members of the APC should see disagreements “within the party as family disputes and should not seek to destroy the platform which helped them in the past.”

“With the huge membership strength we have recorded during the last registration and revalidation exercise, there is no doubt that Nigerians still trust us and that we will win all the upcoming elections convincingly, starting from the governorship elections in Anambra, to Osun, Ekiti, and to the 2023 general election,” he said.

“Therefore, there is a greater need to sustain the trust of our party men and women and indeed all Nigerians.

post-image

President Muhammadu Buhari opened a two-day mid-term ministerial performance review retreat in Abuja on Monday, amid reports that more of his ministers will be sacked for poor performance.

The yearly retreat, which is attended by Ministers, Permanent Secretaries, and other top government officials, is held to evaluate the administration’s top functionaries’ performance.

President Buhari announced the dismissal of two of his ministers during the weekly Federal Executive Council (FEC) meeting on September 1.
They were the Ministers of Power, Engr. Saleh Mamman, and Agriculture and Rural Development, Alhaji Sabo Nanono, at the time, informing others that the action would be ongoing.

According to presidency sources, the President may be waiting for the results of the continuing review process before taking action, which may include removing more of his cabinet members whose performance and conduct do not satisfy the administration’s standards.

President Buhari said he would stay for the entire two-day performance review retreat at…
