We also have serial PCR evaluations showing that individuals who get HPV vaccines prevent HPV infections (or at least promote rapid clearance of the virus) which is a prerequisite for developing cancer:

For our lab's weekly journal club covering classic papers in immunology, we discussed Zheng and Flavell's discovery of GATA3 as a critical transcription factor for Th2 cell cytokine expression.

The Transcription Factor GATA-3 Is Necessary and Sufficient for Th2 Cytokine Gene Expression in CD4 T Cells. Cell, 1997.

Before microarray or RNA-seq, there was cDNA subtraction by representational difference analysis.

The cilium–centrosome axis in coupling cell cycle exit and cell fate

In their Opinion article, @priti_atmakuru and Jyotsna Dhawan discuss the role of the cilium-centrosome complex in tissue homeostasis.

Focussing on the past, the present and the future

Check out the latest in all things FocalPlane in our Editorial from @helenzsci and @seemasainson published in @J_Cell_Sci!

We look back over the three years since FocalPlane was launched and look forward to some exciting projects in 2023 and beyond, including working with our #FocalPlaneCorrespondents.

Whoa. Let’s get back to rationale discussions in brain research:

Debate is vital … The discussion that followed … this is a shame ….

'Writing in Nature, Krishna et al.2 show that malignant gliomas can grow by modifying brain circuitry, thus taking cognitive function away from their host and ultimately leading to death. These insights might lead to fundamentally new approaches to glioma treatment and provide a means of limiting cognitive decline in affected individuals.'

'We demonstrate that while male NK cells display enhanced cellular fitness in mice, they show decreased effector function in mice and humans. These sex biases in NK cell composition and function were not completely due to hormonal differences, because they persisted in gonadectomized mice'

2. There is a very honest description of scientists' motivations. We are all "epistemically sullied", motivated by both curiosity AND desire for recognition.

It is critical to acknowledge this as we seek to reenvisage publishing. Denying the fact (how it drives pursuit of JIF, CNS, h index, competition, etc.) won't help us. The key is to understand this and then think how the system can be improved so distortions (Goodhart's Law, etc.) are minimized.

This is exciting:
"...In this Article, we show that gut-specific telomerase expression in tert−/− zebrafish is sufficient to delay gut aging. Counteracting gut aging improves health of the entire organism, reverting gut microbiota dysbiosis and aging phenotypes in distant organs of tert−/− zebrafish"

"A "very concerning" rise in the number of people catching measles in the UK has been reported by health officials.

The virus spreads incredibly easily and a fall in vaccination rates is leaving more children vulnerable."

Get Vaccinated.
