Day/night variations of myeloid and lymphoid cell subsets in the murine inguinal lymph node

open access: yesFEBS Open Bio, EarlyView.
The circadian system is involved in the temporal regulation of the immune system. Our study reveals that two innate immune populations, NKT cells and neutrophils, predominate at the beginning of the day in healthy mice, highlighting how the time of day influences immune responses.

Conformal Structures Associated to Generic Rank 2 Distributions on 5-Manifolds – Characterization and Killing-Field Decomposition

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
Given a maximally non-integrable 2-distribution D on a 5-manifold M, it was discovered by P. Nurowski that one can naturally associate a conformal structure [g]_D of signature (2,3) on M.

Superalgebras of Dirac operators on manifolds with special Killing-Yano tensors

open access: yes, 2006
We present the properties of new Dirac-type operators generated by real or complex-valued special Killing-Yano tensors that are covariantly constant and represent roots of the metric tensor.

Engineering tandem VHHs to target different epitopes to enhance antibody‐dependent cell‐mediated cytotoxicity

open access: yesFEBS Open Bio, EarlyView.
Tandem VHH targeting distinct EGFR epitopes were engineered into a monovalent bispecific antibody (7D12‐EGA1‐Fc) with more potent ADCC without increasing affinity to EGFR. Structural modeling of 7D12‐EGA1‐Fc showed cross‐linking of separate EGFR domains to enhance CD16a engagement on NK cells.

Polymerization of C9 enhances bacterial cell envelope damage and killing by membrane attack complex pores

open access: yesPLoS Pathogens, 2021
Complement proteins can form membrane attack complex (MAC) pores that directly kill Gram-negative bacteria. MAC pores assemble by stepwise binding of C5b, C6, C7, C8 and finally C9, which can polymerize into a transmembrane ring of up to 18 C9 monomers ...

Classification of supersymmetric spacetimes in eleven dimensions

open access: yes, 2005
We derive, for spacetimes admitting a Spin(7) structure, the general local bosonic solution of the Killing spinor equation of eleven dimensional supergravity.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

The pathology of embryo death caused by the male-killing Spiroplasma bacterium in Drosophila nebulosa

open access: yesBMC Biology, 2007
Background Inherited bacteria that kill male offspring, male-killers, are known to be common in insects, but little is understood about the mechanisms used by male-killing bacteria to kill males. In this paper we describe the tempo and changes that occur

Killing vector fields and characteristic forms

open access: yesJapanese journal of mathematics. New series, 1995
Let \((M,g)\) be a compact orientable Riemannian manifold, \(\dim M =n =2m\), \(\nabla\) the Riemannian connection, \(\omega\) the connection form and \(\Omega =d\omega- \omega\wedge \omega\) the curvature form. The structure group of the tangent bundle of \(M\) is \(SO(n)\), and the corresponding Lie algebra \(o(n)\) is the algebra of real \((n\times ...
