A revolutionary approach into the developement of vaccine to prevent AIDS from mother to babies

"Finding out what protects the majority of babies is very important, because it will cause ways that to spice up natural immune responses and build people proof against HIV infection, aforesaid Peter Kessler, laboratory intern with the Emory University faculty of drugs. Scientists had been speculative for years by the actual fact that solely a minority of babies born to mothers with HIV infection get the infection from their mothers. Currently, HIV infection is with success managed with antiretroviral medicine, however these medicine need to incline for all times. Preventing the infection is incredibly vital, however there's no immunizing agent on the market.
However, Kessler and his colleagues found that levels of Treg lymphocytes were higher within the blood of new born babies born to mothers with HIV infection. World Health Organization had at large the infection themselves, compared with babies World Health Organization were born with HIV infection.
 
Lymphocytes are cells of the system that shield the body by fighting microorganism and viruses. Treg cells also called regulative T cells, help to forestall excessive immune reactions that would cause tissue harm.
The researchers examined the blood of sixty four babies World Health Organization were born HIV-uninfected and twenty eight babies born HIV-infected and located that Treg cell levels were higher in antiseptic babies at the time of birth. In distinction, different WBC sorts were activated and better in HIV-infected infants. The HIV virus will solely infect cells that are activated, therefore Treg might shield from HIV infection by suppressing activation of different lymphocytes.
They analyzed the blood by flow cytometry, a way that may differentiate between the various sorts of cells supported what markers they specific on their surface. regulative T cells are available in several forms with the foremost well-understood being people who specific the markers CD4, CD25, and FOXP3.
these findings indicate that Treg, by dominant immune activation, might lower the vulnerability of the babies to HIV or different chronic infections even before they're born," aforesaid Kessler. These results might pave the method for the event of vaccines or different immune-based therapies that would be used at the side of medications to forestall the unfold of HIV or different infections from mothers to their babies.

Is Habitat Hotspots effective for Transmission of Diseases?

Image
Habitat Hotspots: The un-fold of infectious diseases powerfully depends on however habitat characteristics form patterns of between-host interactions. Specifically, habitat heterogeneousness influences patterns of between-individual contacts and thus, illness dynamics. For instance, “ habitat hotspots ”, sites that attract people or social teams over long distances, may be visited by an outsized set of a population. Around hotspots, between-individual contact rates typically increase in frequency, which amplifies disease transmission . In humans, faculties and dealing places are typical samples of hotspots and are shown to accelerate the un-fold of measles, influenza , and SARS. Thus, limiting transmission at hotspots has become a promising strategy for mitigating epidemics (e.g., influenza) though the potency of such methods additionally depends on the role hotspots play relative to alternative sources of local transmission (e.g., influenza). The un-fold of infectious disea

Is Pneumonia a deadly disease?

Image
Pneumonia is essentially a lung infection that can be serious and life-threatening. The infection can be viral, bacterial or fungal. It causes inflammation in the lungs, wherein alveoli or tiny air sacs inside the lungs get filled with liquid. The key to treating pneumonia and prevent it from getting fatal is early diagnosis and a relatively strong immune system . However, it has to be noted that young children who are weak because of malnutrition are the ones most hit by pneumonia. Pneumonia kills more infants than measles, diarrhea, and malaria combined. Pneumonia has four stages, namely consolidation, red hepatization , grey hepatization and resolution. Symptoms of pneumonia The first symptoms of pneumonia are the same as cold or flu. This is followed by high fever, sputum, chills, and cough. The infection ends in rusty or green phlegm, shortness of breath, chest pain which worsens with taking deep breaths, fatigue and weakness, shortness of breath,

Avian Influenza-An insight

Image
Avian flu refers to a group of infectious diseases caused by influenza viruses that infect birds causing disease. One sub type of Avian Flu is H5N1.  H5N1 is a severe infection with a high mortality rate.The first outbreak  of H5N1 bird  flu  was in December 2003. Since then, over 700 cases have been reported, in Africa, Asia, and Europe with the highest cases reported in Indonesia, Vietnam, and Egypt. The most recent  case of H5N1 was reported in Malaysia in March 2017. It killed a number of chickens, but no human cases were reported. It is not easy for humans to catch it, but it is fatal in 60 percentage  of cases. Symptoms include blood in the sputum, fever, headache  and an upset stomach . Deterioration can be rapid. Antiviral medication can help increase the chances of survival and reduce the impact of the disease. A pandemic is unlikely unless the disease learns to spread between people. What is H5N1?  Type  A strains of the influenza  virus cause H5N1 avian flu.  H5N1 a
