MicroRNA-155, a double-blade sword regulator of innate tuberculosis immunity.

Tuberculosis (TB) is a chronic, life-threatening disease caused by unusual facultative intracellular bacteria, Mycobacterium tuberculosis. This bacterium has unique resistance to many antimicrobial agents and has become a major global health concern due to emerging multidrug-resistant strains. Additionally, it has developed multiple schemes to exploit host immune signaling and establish long-term survival within host tissues.

The interleukin-10 family: Major regulators of the immune response against infections.

Malaria caused by the strain is more severe because of this protozoan's ability to disrupt the physiology of host cells during the blood stages of development by initiating the production of the interleukin-10 (IL-10) family of cytokines. feeds on hemoglobin and causes host cells to adhere to the walls of blood vessels by remodeling their composition. IL-10 is produced by CD4+ T cells that inhibits antigen-presenting cells' activity to prevent inflammation.

Bibliometric Analysis of Publications on the Omicron Variant from 2020 to 2022 in the Scopus Database Using R and VOSviewer.

Human respiratory infections caused by coronaviruses can range from mild to deadly. Although there are numerous studies on coronavirus disease 2019 (COVID-19), few have been published on its Omicron variant. In order to remedy this deficiency, this study undertook a bibliometric analysis of the publishing patterns of studies on the Omicron variant and identified hotspots.

Association of IL28 B and IL10 Polymorphism with HCV Infection and Direct Antiviral Treatment.

Objective: Single nucleotide polymorphisms (SNPs) in IL28B and IL10 regions are important in predicting the antiviral response in hepatitis C virus (HCV) patients. In this study, the association of IL28B and IL10 genetic polymorphisms and other clinical factors was assessed as a predictive marker for the sustained virological response (SVR) of HCV patients taking direct-acting antivirals (DAAs).

Methods: We processed 384 serum specimens of HCV serology positive cases for qualitative and quantitative polymerase chain reaction (PCR).

Molecular Epidemiology of Extensively-Drug Resistant Sequence Type 2 Co-Harboring and From Clinical Origin.

Background: The therapeutic management of carbapenem-resistant (CR-AB) represents a serious challenge to the public health sector because these pathogens are resistant to a wide range of antibiotics, resulting in limited treatment options. The present study was planned to investigate the clonal spread of CR-AB in a clinical setting.

Methodology: A total of 174 clinical isolates were collected from a tertiary care hospitals in Lahore, Pakistan.

Heavy Metal Tolerance Trend in Extended-Spectrum β-Lactamase Encoding Strains Recovered from Food Samples.

This study evaluates bacteriological profiles in ready-to-eat (RTE) foods and assesses antibiotic resistance, extended-spectrum β-lactamase (ESBL) production by gram-negative bacteria, and heavy metal tolerance. In total, 436 retail food samples were collected and cultured. The isolates were screened for ESBL production and molecular detection of ESBL-encoding genes.

Insight into the emerging role of SARS-CoV-2 nonstructural and accessory proteins in modulation of multiple mechanisms of host innate defense.

Coronavirus disease-19 (COVID-19) is an extremely infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has become a major global health concern. The induction of a coordinated immune response is crucial to the elimination of any pathogenic infection. However, SARS-CoV-2 can modulate the host immune system to favor viral adaptation and persistence within the host.

Intelligent Mechanisms of Macrophage Apoptosis Subversion by .

Macrophages are one of the first innate defense barriers and play an indispensable role in communication between innate and adaptive immune responses, leading to restricted () infection. The macrophages can undergo programmed cell death (apoptosis), which is a crucial step to limit the intracellular growth of bacilli by liberating them into extracellular milieu in the form of apoptotic bodies. These bodies can be taken up by the macrophages for the further degradation of bacilli or by the dendritic cells, thereby leading to the activation of T lymphocytes.

Human cytomegalovirus-encoded MicroRNAs: A master regulator of latent infection.

Human cytomegalovirus (HCMV) can modulate the host cell microenvironment to cause latent infection and is therefore considered a major health concern in immunocompromised patients. HCMV-encoded microRNAs (miRs) have emerged as a key player in regulating the expression of the host cell and viral genes to induce latent infection. HCMV-encoded miRs can inhibit antiviral immune responses, such as proinflammatory mediators production, antigenic presentation, and apoptosis.
