H. Ouyang, Y. O. Ali, M. Ravichandran, A. Dong, W. Qiu, F. MacKenzie, S. Dhe-Paganon, C. H. Arrowsmith, R. G. Zhai, Protein aggregates are recruited to aggresome by histone deacetylase 6 via unanchored ubiquitin C termini. J. Biol. Chem. 287, 2317–2327 (2012).
This work suggested a novel ubiquitin-mediated signaling pathway, where the exposure of ubiquitin C termini within protein aggregates enables HDAC6 recognition and transport to the aggresome. The authors found that the ubiquitin-binding domain (ZnF-UBP) of HDAC6, instead of recognizing protein aggregates by binding directly to polyubiquitinated proteins, binds exclusively to the unanchored C-terminal diglycine motif of ubiquitin.
Y. Zhang, B. Gilquin, S. Khochbin, P. Matthias, Two catalytic domains are required for protein deacetylation. J. Biol. Chem. 281, 2401–2404 (2006).
In this report, the authors showed that both HDAC domains are required for the intact deacetylase activity of HDAC-6.

Matthias, Mice lacking histone deacetylase 6 have hyperacetylated tubulin but are viable and develop normally. Mol. Cell. Biol. 28, 1688–1701 (2008). doi:10.1128/MCB.01154-06 pmid:18180281
In this study, the author generated HDAC6 knock out mice and investigated the in vivo functions of HDAC6 and the relevance of tubulin acetylation/deacetylation. they observed that HDAC6-deficient mice are viable and fertile and show hyperacetylated tubulin in most tissues.They concluded that mice survive well without HDAC6 and that tubulin hyperacetylation is not detrimental to normal mammalian development.
I. Kemler, G. Whittaker, A. Helenius, Nuclear import of microinjected influenza virus ribonucleoproteins. Virology 202, 1028–1033 (1994).
This work showed that when influenza virus ribonucleoproteins (vRNPs), devoid of M1, were introduced into the cytoplasm of cells by microinjection, they were found to be imported into the nucleus, and the RNA was transcribed. Their uptake into the nucleus was ATP-dependent, inhibited by antibodies to the nuclear pore complex, unaffected by the prior acidification of the vRNPs, and not inhibited by an anti-virurs, called amantadine. These experiments demonstrated that for productive infection, all the early stages of the viral entry pathway can be bypassed.

This study provides a powerful high-throughput platform to understand the host cell processes. The authors developed quantitative, imaging-based assays to dissect seven consecutive steps in the early phases of IAV infection in tissue culture cells.

This work investigated the cell fusion process of representatives of 3 families of enveloped viruses. it was discovered that hemagglutinin plays a role for the influenza in the low-pH-dependent membrane fusion activity. Low-pH-induced fusion is a widespread property of enveloped animal viruses and that it may play a role in the infective process.

K. Martin, A. Helenius, Nuclear transport of influenza virus ribonucleoproteins: The viral matrix protein (M1) promotes export and inhibits import. Cell 67, 117–130 (1991). doi:10.1016/0092-8674(91)90576-K pmid:1913813
This work described the nuclear transport of influenza virus ribonucleoproteins (vRNPs). Viral matrix protein (M1) associates with newly assembled vRNPs in the nucleus and escorts them to the cytoplasm through the nuclear pores. In contrast, during entry of the virus into a new host cell, M1 protein dissociates from the RNPs, allowing them to enter the nucleus.

This study is about animal domestication. It explains that the dog is the only animal domesticated before the advent of agriculture. It also discuss the limits of mtDNA analysis.
First, the domain is a poor candidate because the domain of all entities relevant to neurobiological function is extremely large, highly fragmented into separate subdisciplines, and riddled with lack of consensus (Shirky, 2005).
