Article Synopsis
  • T2 cells and innate lymphoid cells 2 (ILC2) can promote tumor growth by producing cytokines like IL-4, IL-5, and IL-13, but how these immune cells reach tumors is unclear.
  • This study reveals that oncogenic Kras enhances IL-33 levels in pancreatic ductal adenocarcinoma (PDAC) cells, which helps recruit and activate T2 and ILC2 cells, with deletion of IL-33 leading to reduced recruitment and tumor slowdown.
  • Interestingly, IL-33 secretion relies on the presence of intratumoral fungi, and blocking IL-33 or treating with anti-fungal methods can reduce T2 and ILC2 cell infiltration, potentially improving survival rates in

In the absence of a consensus protocol to slow down the spread of SARS-CoV-2, policymakers need real-time indicators to support decisions in public health matters. The Effective Reproduction Number ( ) represents the number of secondary infections generated per each case and can be dramatically modified by applying effective interventions. However, current methodologies to calculate from data remain somewhat cumbersome, thus raising a barrier between its timely calculation and application by policymakers.

COVID-19 pandemic has reshaped our world in a timescale much shorter than what we can understand. Particularities of SARS-CoV-2, such as its persistence in surfaces and the lack of a curative treatment or vaccine against COVID-19, have pushed authorities to apply restrictive policies to control its spreading. As data drove most of the decisions made in this global contingency, their quality is a critical variable for decision-making actors, and therefore should be carefully curated.

The outbreak and propagation of COVID-19 have posed a considerable challenge to modern society. In particular, the different restrictive actions taken by governments to prevent the spread of the virus have changed the way humans interact and conceive interaction. Due to geographical, behavioral, or economic factors, different sub-groups among a population are more (or less) likely to interact, and thus to spread/acquire the virus.

Context: High-grade T1 (T1HG) bladder cancer (BCa) has a very high likelihood of disease recurrence and progression to muscle invasion. Radical cystectomy is considered the best chance at cure, albeit with a high risk of morbidity, and is overtreatment for some patients. Treatment with bacillus Calmette-Guerin (BCG) allows bladder preservation but may risk disease progression.
