The present invention provides methods and compositions for the remote control of cell function based on the use of a magnetic field to excite paramagnetic nanoparticles targeted to specific cell types. The cell type of interest expresses an ion channel wherein excitation of the paramagnetic nanoparticles results in a physical change that is transduced into a cellular response. Such cellular responses may include, for example, increases in gene expression resulting in production of one or more physiologically active proteins. The expression of such proteins can be used to treat a variety of different inherited or acquired diseases or disorders in a subject.

The invention provides a polypeptide containing at least one IgG Fc region, wherein said at least one IgG Fc region is glycosylated with at least one galactose moiety connected to a respective terminal sialic acid moiety by a 2,6 linkage, and wherein said polypeptide having a higher anti-inflammatory activity as compared to an unpurified antibody.

Provided are compositions and methods for producing large repertoires of recombinant nanobodies with high affinities and specificities against any antigen. Included are methods for making and identifying nanobodies produced by camelids, the nanobodies themselves, modifications of the nanobodies, expression vectors encoding the nanobodies, cDNAs encoding the nanobodies, cells comprising the expression vectors and/or cDNA, and methods of making the nanobodies recombinantly. Antigen-specific nanobodies and antigen binding fragments thereof having a Kd for the antigen in a sub-micromolar range are provided.

Prokaryotic organisms are threatened by a large array of viruses and have developed numerous defence strategies. Among these, only clustered, regularly interspaced short palindromic repeat (CRISPR)-Cas systems provide adaptive immunity against foreign elements. Upon viral injection, a small sequence of the viral genome, known as a spacer, is integrated into the CRISPR locus to immunize the host cell. Spacers are transcribed into small RNA guides that direct the cleavage of the viral DNA by Cas nucleases. Immunization through spacer acquisition enables a unique form of evolution whereby a population not only rapidly acquires resistance to its predators but also passes this resistance mechanism vertically to its progeny. © 2015 Macmillan Publishers Limited.

In eukaryotes, chromosome segregation during cell division is facilitated by the kinetochore, a multiprotein structure that is assembled on centromeric DNA. The kinetochore attaches chromosomes to spindle microtubules, modulates the stability of these attachments and relays the microtubule-binding status to the spindle assembly checkpoint (SAC), a cell cycle surveillance pathway that delays chromosome segregation in response to unattached kinetochores. Recent studies are shaping current thinking on how each of these kinetochore-centred processes is achieved, and how their integration ensures faithful chromosome segregation, focusing on the essential roles of kinase-phosphatase signalling and the microtubule-binding KMN protein network. © 2012 Macmillan Publishers Limited.

A properly functioning adaptive immune system signifies the best features of life. It is diverse beyond compare, tolerant without fail, and capable of behaving appropriately with a myriad of infections and other challenges. Dendritic cells are required to explain how this remarkable system is energized and directed. I frame this article in terms of the major decisions that my colleagues and I have made in dendritic cell science and some of the guiding themes at the time the decisions were made. As a result of progress worldwide, there is now evidence of a central role for dendritic cells in initiating antigen-specific immunity and tolerance. The in vivo distribution and development of a previously unrecognized white cell lineage is better understood, as is the importance of dendritic cell maturation to link innate and adaptive immunity in response to many stimuli. Our current focus is on antigen uptake receptors on dendritic cells. These receptors enable experiments involving selective targeting of antigens in situ and new approaches to vaccine design in preclinical and clinical systems. © 2012 by Annual Reviews.

Mass spectrometry (MS) is rapidly becoming an essential tool for biologists and biochemists in their efforts to throw light on molecular mechanisms within cellular systems. Used in unison with genome sequence data, MS has developed into the method of choice for identifying proteins, elucidating their posttranslational modifications, and reading out their functional interactions. Variations of the method have even begun to enable accurate mass determination of intact protein complexes, allowing for direct determination of subunit stoichiometry and the interactions between the subunits. Advances in mass spectrometric technologies have also led to great improvements in our ability to probe and define many of the other key molecular players in cells, including the all important lipid components. We provide here some perspectives on the explosion of applications of MS to protein science, systems biology, proteomics, lipidomics, and cell biology in general. © 2011 by Annual Reviews.
