Previously we reported the role of zebrafish (ZF) encoded glucosaminyl 3-O-sulfotransferase-3 (3-OST-3) isoform in assisting herpes simplex virus type-1 (HSV-1) entry and spread by generating an entry receptor to HSV-1 envelope glycoprotein D (gD). However, the ability of ZF encoded 3-OST-2 isoform to participate in HSV-1 entry has not been determined although it is predominantly expressed in ZF brain, a prime target for HSV-1 to infect and establish lifelong latency. Here we report the expression cloning of ZF encoded 3-OST-2 isoform and demonstrate HSV-1 entry into resistant Chinese hamster ovary (CHO-K1) cells expressing the clone. Additional significance of ZF encoded 3-OST-2 receptor was demonstrated using medically important isolates of HSV-1. In addition, interference to HSV-1 entry was observed upon co-expression of HSV-1 gD and ZF 3-OST-2. Similarly HSV-1 entry was significantly inhibited by the pre-treatment of cells with enzyme HS lyases (heparinase II/III). Finally, ZF-3-OST-2 expressing CHO-K1 was able to fuse with HSV-1 glycoprotein expressing cells suggesting their role in HSV-1 spread. Taken together our result demonstrates a role for ZF 3-OST-2 in HSV-1 pathogenesis. (C) 2013 Elsevier Inc. All rights reserved.

OPTN (optineurin)-mediated selective autophagy prevents neurodegeneration due to herpesvirus infection

Chandrashekhar D. Patil, Deepak Shukla

Summary: Very little is known about the mechanisms that restrict neurotropic herpesviruses from infecting the central nervous system and causing neuron death. However, recent research has shown that OPTN-mediated autophagy acts as an intrinsic immune barrier against these viruses and protects the CNS from neurodegenerative stress.

Intrinsic Antiviral Activity of Optineurin Prevents Hyperproliferation of a Primary Herpes Simplex Virus Type 2 Infection

Summary: This study reveals the key role of optineurin (OPTN) in restricting HSV-2 infection and controlling viral spread. Lack of OPTN leads to enhanced virus production and impaired host autophagy response. The OPTN/CCL5 nexus identified in this study may represent an intrinsic host defense mechanism against herpesviruses.

Optineurin in ocular herpes infection

Earon Grinage, Deepak Shukla

Summary: This review summarizes the crucial role of host protein Optineurin during HSV-1 infection of the eye and the nervous system. Recent studies have shown that Optineurin can prevent cell-to-cell spread of the virus and protect the nervous system from damage. Therefore, Optineurin may be a key factor in preventing ocular and neurodegenerative diseases.

Archaic connectivity between the sulfated heparan sulfate and the herpesviruses-An evolutionary potential for cross-species interactions

James Elste, Angelica Chan, Chandrashekhar Patil, Vinisha Tripathi, Daniel M. Shadrack, Dinesh Jaishankar, Andrew Hawkey, Michelle Swanson Mungerson, Deepak Shukla, Vaibhav Tiwari

Summary: The structural diversity of heparan sulfate (HS) in various vertebrates and invertebrates is remarkably preserved and plays a key role in ligand binding and virus entry. The interaction between glycoprotein D (gD) from herpes simplex virus (HSV) and 3-O sulfated HS leads to virus-cell fusion and HSV entry. HSV-1, which infects a large number of people worldwide, can also cause severe diseases in both primates and non-primates. The enzymatic modification of HS by 3-O sulfotransferase-3 (3-OST-3) enhances HSV-1 infectivity and suggests a possible role of HS in cross-species transmission.

Neutrophil Extracellular Traps and Their Possible Implications in Ocular Herpes Infection

Divya Kapoor, Deepak Shukla

Summary: Neutrophil extracellular traps (NETs) are net-like structures released from neutrophils mainly containing cell-free DNA decorated with histones and neutrophil granule proteins. NETs can be induced by various stimuli such as pathogens, cytokines, and immune complexes. They have both beneficial and detrimental effects in capturing pathogens and aggravating inflammation. This review focuses on the formation mechanism of NETs in different ocular pathologies, particularly highlighting their potential implications during herpes simplex virus (HSV) ocular infections and as prospective targets for ocular disease treatment.

Summary: Cancer burden is increasing rapidly globally, with lifestyle factors such as unhealthy diet being major contributors. The specific fatty acids that contribute to a healthy and balanced diet in terms of cancer risk and prognosis are still unclear. This review explores the associations between intake of different fatty acids and cancer risk, as well as the effects of specific fatty acids on tumor cells and inflammation-induced cancer progression, highlighting challenges and opportunities for fatty acid tailored nutritional interventions.

Pathophysiology of reinfection by exogenous HSV-1 is driven by heparanase dysfunction

Rahul K. Suryawanshi, Chandrashekhar D. Patil, Alex Agelidis, Raghuram Koganti, Tejabhiram Yadavalli, Joshua M. Ames, Hemant Borase, Deepak Shukla

Summary: This study found that compared to animals lacking HPSE, wild-type mice exhibit notable pathophysiology during HSV-1 reinfection. HPSE promotes infected cell survival and supports the formation of a pro-disease environment. In contrast, lack of HPSE enhances intrinsic immunity by promoting cytokine expression, inducing necroptosis of infected cells, and decreasing leukocyte infiltration into the cornea. Overall, recent prior infection immunity fails to abolish disease manifestation during HSV-1 reinfection unless HPSE is rendered inactive.

Hole behavior captured by analysis of instantaneous amplitude and phase of sarcosynced oscillations reveals wave characteristics of sarcomeric oscillations

Seine A. Shintani

Summary: In this study, the researchers used signal analysis to study the instantaneous amplitude and phase of sarcomeric oscillations in skeletal muscle. They identified two types of oscillations, sarcomeric oscillations and sarcosynced oscillations, and visualized their behavior during propagating waves. The researchers discovered the presence of sarcomeric defect holes and sarcomeric collision holes, which are important indicators for understanding the oscillation properties of sarcomeres. This finding has important implications for improving our understanding of muscle function and its regulatory mechanisms.

TP53INP2 modulates the malignant progression of colorectal cancer by reducing the inactive form of β-catenin

Ke Shi, Yunlong Shan, Xiao Sun, Kuida Chen, Qiong Luo, Qiang Xu

Summary: This study found that low expression of TP53INP2 is associated with poor survival in colorectal cancer (CRC) patients. As the malignancy of CRC progresses, TP53INP2 expression gradually decreases. Knockdown of TP53INP2 promotes CRC cell proliferation and tumor growth. Mechanistically, TP53INP2 deficiency decreases phosphorylation of beta-catenin, leading to increased accumulation and enhanced nuclear translocation and transcriptional activity. Additionally, TP53INP2 sequesters TIM50, inhibiting its activation of beta-catenin. In conclusion, downregulation of TP53INP2 promotes CRC progression by activating beta-catenin.

The four subunits of rabbit skeletal muscle lactate dehydrogenase do not exert their catalytic action additively

Martina Rossi, Fabio Tomaselli, Alejandro Hochkoeppler

Summary: Oligomeric enzymes are known for their higher catalytic rates compared to monomeric enzymes, but the extent of additivity in their activity is still not well understood. This study used tetrameric rabbit lactate dehydrogenase as a model to examine the kinetics of its catalytic action. Surprisingly, when the concentration of the limiting reactant exceeded that of a single subunit, there was a significant slowdown in the enzyme's conformational rearrangements.
