In a study of the immune systems of mice, scientists at Johns Hopkins Medicine say they have found a new role for a protein, QRICH1, which could become a target for drugs to dial up or down the activation of T cells to fight cancers and autoimmune diseases.

Un equipo de astr贸nomos construy贸 una representaci贸n tridimensional del asteroide 2024 YR4, que fue descubierto recientemente y que se encuentra en las proximidades de la Tierra. Los cient铆ficos, adem谩s determinaron que el objeto se origin贸 en el cintur贸n principal de asteroides del Sistema Solar, gracias a las observaciones realizadas desde Chile con el telescopio Gemini Sur, la mitad austral del Observatorio Internacional Gemini de la Fundaci贸n Nacional de Ciencias de Estados Unidos y operado por NOIRLab de NSF. Los investigadores tambi茅n confirmaron que esta roca espacial de forma inusual, es uno de los objetos m谩s grandes de la historia reciente que podr铆a impactar a la Luna.

Using observations from the Gemini South telescope in Chile, one half of the International Gemini Observatory, partly funded by the U.S. National Science Foundation and operated by NSF NOIRLab, astronomers have constructed a 3D representation of the newly discovered near-Earth asteroid 2024 YR4. The team determined that the unusually-shaped rock is one of the largest objects in recent history that could impact the Moon, and that it likely originated from the main asteroid belt.

A preclinical model developed at UT Southwestern Medical Center that recapitulates a rare infant-onset form of diabetes suggests the condition stems from gradual damage to the pancreas through misregulation of a molecular pathway called the unfolded protein response (UPR). The findings, published in Molecular Metabolism, could one day lead to new ways to treat more common subsets of diabetes, including Types 1 and 2, which affect hundreds of millions worldwide.

A recent publication in the International Journal of Cardiology, Pulmonary artery denervation in pulmonary hypertension: A comprehensive meta-analysis, has shed light on the potential of pulmonary artery denervation (PADN) as an innovative intervention for pulmonary hypertension (PH), a condition that places patients at risk for right heart failure and death.

In this study, we show that transcriptional regulators, previously linked to development in Caenorhabditis elegans, also control immune responses. Through forward genetic screens, we found that loss of LIN-15B leads to constitutive activation of Intracellular Pathogen Response (IPR) genes. LIN-15B is functionally associated with the DREAM chromatin remodeling complex, and its loss enhances resistance to intracellular pathogens. This immune response depends on the MES-4 histone methyltransferase. We also discovered that other chromatin regulators, including NuRD and SUMOylation factors, similarly repress IPR gene expression, highlighting a new role in immunity for these conserved regulators of development.
