Macrophage Proteomic Profiling Reveals Divergent TLR4-Dependent and -Independent Responses to Kdo₂-Lipid A and Lipid IVa

Life
Macrophages harness pattern recognition receptors (PRRs) to detect conserved bacterial components and mount effective immune responses. Many Gram-negative bacteria modify their lipid A structures to limit recognition by Toll-like receptor 4 (TLR4) and ...

When natural mutants do not fit our expectations: the intriguing case of patients with XRCC4 mutations revealed by whole‐exome sequencing

EMBO Molecular Medicine, 2015
Mutations in the XRCC4 gene have been recently identified through whole‐exome sequencing (WES). While the overall clinical presentation of the patients (severe short stature, microcephaly, gonadal failure) generally conforms with what is expected for the

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Trends in physiological role of opioids in psychoneuroendocrine-immune network.

, 1994
Extensive evidence suggests that opioid influences on the immune response are mediated through opioid receptors on the surface of immune cells. In addition, the binding of opioid agonists to centrally located opioid receptors appears also to alter immune

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Structural mechanism of anti-MHC-I antibody blocking of inhibitory NK cell receptors in tumor immunity

Communications Biology
Anti-major histocompatibility complex class I (MHC-I) mAbs can stimulate immune responses to tumors and infections by blocking suppressive signals delivered via various immune inhibitory receptors.

PARP Inhibition Shifts Murine Myeloid Cells Toward a More Tolerogenic Profile In Vivo

Biomolecules
The human Poly ADP-ribose Polymerase (PARP) family comprises 17 enzymes responsible for the transfer of ADP-ribose to proteins, forming poly- or mono-ADP-ribosylation.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...
