Regulation and Roles of Metacyclogenesis and Epimastigogenesis in the Life Cycle of Trypanosoma cruzi

Pathogens
Trypanosoma cruzi, the etiological agent of Chagas disease, exhibits remarkable developmental plasticity that enables its survival across distinct environments within the insect vector and mammalian host.

Chlamydia trachomatis Inclusion Membrane Protein CT228 Recruits Elements of the Myosin Phosphatase Pathway to Regulate Release Mechanisms

Cell Reports, 2013
Chlamydia trachomatis replicates within a membrane-bound compartment termed an inclusion. The inclusion membrane is modified by the insertion of multiple proteins known as Incs. In a yeast two-hybrid screen, an interaction was found between the inclusion

The evolutionary and coevolutionary consequences of defensive microbes for host-parasite interactions

BMC Evolutionary Biology, 2017
Animal and plant species can harbour microbes that provide them with protection against enemies. These beneficial microbes can be a significant component of host defence that complement or replaces a repertoire of immunity, but they can also be costly ...

Parasites lead to evolution of robustness against gene loss in host signaling networks [PDF]

, 2008
Many biological networks can maintain their function against single gene loss. However, the evolutionary mechanisms responsible for such robustness remain unclear.

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

Advanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

The evolution of covert, silent infection as a parasite strategy [PDF]

, 2009
Many parasites and pathogens cause silent/covert infections in addition to the more obvious infectious disease-causing pathology. Here, we consider how assumptions concerning superinfection, protection and seasonal host birth and transmission rates ...

Designing Polymer Nanocomposites for X‐Ray Shielding: Mechanisms, Architectures, and Scalable Processing

Advanced Engineering Materials, EarlyView.
This review highlights advances in lightweight, lead‐free polymer nanocomposites for diagnostic X‐ray shielding. By linking filler chemistry, dispersion, architecture, and photon interaction mechanisms, it establishes structure–performance relationships guiding material design.

Extracellular Vesicles Mediate Epimastigogenesis in Trypanosoma cruzi: Strain-Specific Dynamics and Temperature-Dependent Differentiation

Life
Trypanosoma cruzi, the causative agent of Chagas disease, undergoes epimastigogenesis—a critical differentiation step in which trypomastigotes transform into epimastigotes. While this process is essential for the parasite’s survival in its insect vector,

Characterization of a Toxoplasma effector uncovers an alternative GSK3/β-catenin-regulatory pathway of inflammation

eLife, 2018
The intracellular parasite Toxoplasma gondii, hijacks evolutionarily conserved host processes by delivering effector proteins into the host cell that shift gene expression in a timely fashion.

Responses of a bacterial pathogen to phosphorus limitation of its aquatic invertebrate host [PDF]

, 2008
Host nutrition is thought to affect the establishment, persistence, and severity of pathogenic infections. Nutrient-deficient foods possibly benefit pathogens by constraining host immune function or benefit hosts by limiting parasite growth and ...
