Scientists have pinpointed genetic changes that can leave children born with little to no immune defence against infection.
While newborn screening methods can flag T cell deficiency, knowledge of the specific genetic cause increases confidence in the diagnosis of SCID and informs the choice of curative therapy. Currently this remains out of reach for at least 1 in 10 affected families. Dr Gosia Trynka, author of the study at the Wellcome Sanger Institute and science director at Open Targets, said:"For babies born with high-risk immunodeficiencies, early detection can mean the difference between life and death. These diseases leave newborns essentially defenceless against pathogens that most of us can easily fend off.
2. Specifically, the mutant NUDCD3 could not regulate RAG1, a key enzyme needed in VJ recombination. This caused RAG1 to get trapped within cell nucleoli instead of facilitating the gene rearrangements that build immune diversity.Rui Chen, Elena Lukianova, Ina Schim van der Loeff, Jarmila Stremenova Spegarova, Joseph D.P.

Researchers develop genetic plant regeneration approach without the application of phytohormonesFor ages now, plants have been the primary source of nutrition for animals and mankind. Additionally, plants are used for the extraction of various medicinal and therapeutic compounds. However, their indiscriminate use, along with the rising demand for food, underscores the need for novel plant breeding practices.

Researchers decipher how an enzyme modifies the genetic material in the cell nucleusInside the cell nucleus, the DNA molecule is found in a densely packed DNA-protein complex known as chromatin. Here the DNA is wrapped around a core of histone proteins and densely packed to form nucleosomes. The structure of the nucleosomes determines which genes are accessible and active and therefore plays an important role in gene regulation.
