22, 2025 — Pathogen-fighting immune cells called tissue-resident memory CD8 T cells (TRM cells) go through a surprising transformation -- and relocation -- as they fight infections in the small ...

Jan. 15, 2025 — While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows.

Leica Microsystems now sells an STED microscope with a resolution of 80 nm. At present, the far-field methods are those chosen for imaging structures below a surface, such as inside a cell.

DAPI and WGA 488 were acquired in confocal mode and images of MPO (STAR RED) and IL-40 (STAR 580) in cell detail were acquired using stimulated emission depletion (STED) microscopy. The imaging was ...

“完整穿越”模型的提出从根本上改变了我们对HIV感染过程的理解。传统假设认为，病毒通过解体将基因组暴露给宿主，这一过程是被动的、低效的。而新的研究揭示，病毒具有高度精确的“入侵策略”，包括巧妙利用衣壳结构与宿主核孔的相互作用，从而实现基因组的高效传递 ...

and technical consultant bodies having high credibility out of extensive work accomplished and proven history of promotion and development of technology-based services may submit the i-STED proposal.

These regulators are known as MYB, HDAC2, and FOXA2 and when they were suppressed in colon cancer cells, the cells switched back to a normal-like state, removing the cancer threat without ...

Using this approach, we successfully reconstructed morphologies and life cycles of Archaean microfossils. In addition to reproducing microfossil morphologies, we conducted experiments that spanned ...

However, for high-resolution imaging to investigate molecular interactions or small structures within cells, super-resolution microscopy would be a better option. Super-resolution microscopy (e.g., ...
