  • Monoclonal Antibodies As Tools to Combat Fungal Infections
    Journal of Fungi Review Monoclonal Antibodies as Tools to Combat Fungal Infections Sebastian Ulrich and Frank Ebel * Institute for Infectious Diseases and Zoonoses, Faculty of Veterinary Medicine, Ludwig-Maximilians-University, D-80539 Munich, Germany; [email protected] * Correspondence: [email protected] Received: 26 November 2019; Accepted: 31 January 2020; Published: 4 February 2020 Abstract: Antibodies represent an important element in the adaptive immune response and a major tool to eliminate microbial pathogens. For many bacterial and viral infections, efficient vaccines exist, but not for fungal pathogens. For a long time, antibodies have been assumed to be of minor importance for a successful clearance of fungal infections; however this perception has been challenged by a large number of studies over the last three decades. In this review, we focus on the potential therapeutic and prophylactic use of monoclonal antibodies. Since systemic mycoses normally occur in severely immunocompromised patients, a passive immunization using monoclonal antibodies is a promising approach to directly attack the fungal pathogen and/or to activate and strengthen the residual antifungal immune response in these patients. Keywords: monoclonal antibodies; invasive fungal infections; therapy; prophylaxis; opsonization 1. Introduction Fungal pathogens represent a major threat for immunocompromised individuals [1]. Mortality rates associated with deep mycoses are generally high, reflecting shortcomings in diagnostics as well as limited and often insufficient treatment options. Apart from the development of novel antifungal agents, it is a promising approach to activate antimicrobial mechanisms employed by the immune system to eliminate microbial intruders. Antibodies represent a major tool to mark and combat microbes. Moreover, monoclonal antibodies (mAbs) are highly specific reagents that opened new avenues for the treatment of cancer and other diseases.

TRAVASSOS ABSTRACT For a long time sporotrichosis has been regarded to have a low incidence in Brazil; however, recent studies demonstrate that not only the number of reported cases but also the incidence of more severe or atypical clinical forms of the disease are increasing. Recent data indicate that these more severe forms occur in about 10% of patients with confirmed diagnosis. The less frequent forms, mainly osteoarticular sporotrichosis, might be associated both with patient immunodepression and zoonotic transmission of the disease. The extracutaneous form and the atypical forms are a challenge to a newly developed serological test, introduced as an auxiliary tool for the diagnosis of unusual clinical forms of sporotrichosis.

  • Davis Overview of Fungi and Diseases 2014
    JHH ID Tutorials Dr Josh Davis December 2014 MYCOLOGY OVERVIEW 1. OVERVIEW. It is estimated that there are 1.5 million extant species of fungi on Earth, of which 60,000 have been described/named; of these only approximately 400 species have ever been described to cause disease in humans and only approximately 20 do so with any frequency. Many others are plant pathogens or symbionts. At least 13,500 fungal species form lichens, symbiotic partnerships between fungi (usually ascomycota) and photosynthetic microbes (eg. algae, cyanobacteria). 2. CLASSIFICATION. There are several confusing/overlapping classifications systems for fungi. 2.1 Biological Kingdom FUNGI; Phyla: 2.1.1 Phylum Zygomycota – Agents of zygomycosis, “mucormycosis”. Most primitive fungi. Broad, ribbon-like hyphae, no septae. Generally grow fast on agar (“lid-lifters”). 2.1.1.1 Order Mucorales – eg. Rhizopus, Rhizomucor, Mucor, Saskanaea, Cuninghamella 2.1.1.2 Order Entomophthorales – Basidiobolus, Canidiobolus 2.1.2 Phylum Basidiomycota – Mushrooms, jelly fungi, smuts, rusts, stinkhorns . and the teleomorph of cryptococcus! 2.1.3 Phylum Ascomycota – e.g. Pseudoallescheria, Curvularia, Saccharomyces. 2.1.4 Phylum Deuteromycota, or Fungi Imperfecti. Not a true phylum. Contains asexual (“imperfect”) forms of fungi (anamorphs), most of which have not had a sexual form described. Most human pathogens are in this group – eg: Aspergillus, Candida, Cryptococcus, Scedosporium, Alternaria, Trichophyton, Cladosporium etc. etc. 1. Sporotrix at 37 and 25 degrees; 2. Aspergillus fumigatus, niger, terreus, flavus (L to R); 3. Candida albicans 2.2 Morphological 2.2.1 Broad classification - Yeasts, Moulds and Dimorphic Fungi 2.2.1.1 Yeasts are single-celled organisms which reproduce by budding and grow as smooth colonies on agar.

The HIV/AIDS pandemic, particularly in China and other Southeast Asian countries, has led to the emergence of P. marneffei infection as an important AIDS-defining condition. Recently, we published the genome sequence of P. marneffei. In the P. marneffei genome, 23 polyketide synthase genes and two polyketide synthase-non-ribosomal peptide synthase hybrid genes were identified.

  • Characterization of a Novel Yeast Phase-Specific Antigen Expressed
    www.nature.com/scientificreports OPEN Characterization of a novel yeast phase‑specifc antigen expressed during in vitro thermal phase transition of Talaromyces marnefei Kritsada Pruksaphon1, Mc Millan Nicol Ching2,3, Joshua D. Nosanchuk4, Anna Kaltsas5,6, Kavi Ratanabanangkoon7, Sittiruk Roytrakul8, Luis R. Martinez9 & Sirida Youngchim10* Talaromyces marnefei is a dimorphic fungus that has emerged as an opportunistic pathogen particularly in individuals with HIV/AIDS. Since its dimorphism has been associated with its virulence, the transition from mold to yeast‑like cells might be important for fungal pathogenesis, including its survival inside of phagocytic host cells. We investigated the expression of yeast antigen of T. marnefei using a yeast‑specifc monoclonal antibody (MAb) 4D1 during phase transition. We found that MAb 4D1 recognizes and binds to antigenic epitopes on the surface of yeast cells. Antibody to antigenic determinant binding was associated with time of exposure, mold to yeast conversion, and mammalian temperature. We also demonstrated that MAb 4D1 binds to and recognizes conidia to yeast cells’ transition inside of a human monocyte‑like THP‑1 cells line. Our studies are important because we demonstrated that MAb 4D1 can be used as a tool to study T. marnefei virulence, furthering the understanding of the therapeutic potential of passive immunity in this fungal pathogenesis. Te thermally dimorphic fungus Talaromyces (Penicillium) marnefei causes a life-threatening systemic mycosis in immunocompromised individuals living in or traveling to Southeast Asia, mainland of China, and the Indian sub-continents. Talaromyces marnefei is a distinctive species in the genus. It is the only one species capable of thermal dimorphism.

A number of mycoses associated with zoonotic transmission are among the group of the most common fungal diseases, worldwide. It is, however, notable that some fungal diseases with zoonotic potential have lacked adequate attention in international public health efforts, leading to insufficient attention on their preventive strategies. This review aims to highlight some mycoses whose zoonotic potential received less attention, including infections caused by Talaromyces (Penicillium) marneffei, Lacazia loboi, Emmonsia spp., Basidiobolus ranarum, Conidiobolus spp.

Abstract: Infections caused by the opportunistic pathogens Scedosporium/Lomentospora are on the rise. This causes problems in the clinic due to the difficulty in diagnosing and treating them. This review collates information published on immune response against these fungi, since an understanding of the mechanisms involved is of great interest in developing more effective strategies against them. Sce- dosporium/Lomentospora cell wall components, including peptidorhamnomannans (PRMs), α-glucans and glucosylceramides, are important immune response activators following their recognition by TLR2, TLR4 and Dectin-1 and through receptors that are yet unknown. After recognition, cytokine synthesis and antifungal activity of different phagocytes and epithelial cells is species-specific, high- lighting the poor response by microglial cells against L. prolificans. Moreover, a great number of Scedosporium/Lomentospora antigens have been identified, most notably catalase, PRM and Hsp70 for their potential medical applicability. Against host immune response, these fungi contain evasion mechanisms, inducing host non-protective response, masking fungal molecular patterns, destructing host defense proteins and decreasing oxidative killing.

It has gained importance in recent years due to its worldwide preva- lence, recognition of multiple cryptic species within the originally described species, and its distinctive ecology, distribution, and epidemiology across the globe. In this review, we describe the current knowledge of the taxonomy, ecology, prevalence, molecular epi- demiology, and outbreaks due to S. schenckii sensu lato. Despite its omnipresence in the environment, this fungus has remarkably diverse modes of infection and distribution patterns across the world. We have delved into the nuances of how sporotrichosis is intimately linked to different forms of human activities, habitats, lifestyles, and environ- mental and zoonotic interactions.
