Abstract
Lectins are proteins widely distributed among plants, animals and microorganisms that have the ability to recognize and interact with specific carbohydrates. They have varied biological activities, such as the inhibition of the progression of infections caused by fungi, bacteria, viruses and protozoa, which is related to the interaction of these proteins with the carbohydrates present in the cell walls of these microorganisms. Leishmaniasis are a group of endemic infectious diseases caused by protozoa of the genus Leishmania. In vitro and in vivo tests with promastigotes and amastigotes of Leishmania demonstrated that lectins have the ability to interact with glycoconjugates present on the cell surface of the parasite, it prevents their development through various mechanisms of action, such as the production of ROS and alteration of membrane integrity, and can also interact with defense cells present in the human body, thus showing that these molecules can be considered alternative pharmacological targets for the treatment of leishmaniasis. The objective of the present work is to carry out a bibliographic review on lectins with leishmanicidal activity, emphasizing the advances and perspectives of research in this theme. Through the analysis of the selected studies, we were able to conclude that lectins have great potential for inhibiting the development of leishmaniasis. However, there are still few studies on this subject.

Abstract
Lipophosphoglycan (LPG), the major Leishmania glycoconjugate, induces pro-inflammatory/immunosuppressive innate immune responses. Here, we evaluated functional/biochemical LPG properties from six Leishmania amazonensis strains from different hosts/clinical forms. LPGs from three strains (GV02, BA276, and LV79) had higher pro-inflammatory profiles for most of the mediators, including tumor necrosis factor alpha and interleukin 6. For this reason, glycoconjugates from all strains were biochemically characterized and had polymorphisms in their repeat units. They consisted of three types: type I, repeat units devoid of side chains; type II, containing galactosylated side chains; and type III, containing glucosylated side chains. No relationship was observed between LPG type and the pro-inflammatory properties. Finally, to evaluate the susceptibility against antileishmanial agents, two strains with high (GV02, BA276) and one with low (BA336) pro-inflammatory activity were selected for chemotherapeutic tests in THP-1 cells. All analyzed strains were susceptible to amphotericin B (AmB) but displayed various responses against miltefosine (MIL) and glucantime (GLU). The GV02 strain (canine visceral leishmaniasis) had the highest IC50 for MIL (3.34 μM), whereas diffuse leishmaniasis strains (BA276 and BA336) had a higher IC50 for GLU (6.87-12.19 mM). The highest IC50 against MIL shown by the GV02 strain has an impact on clinical management. Miltefosine is the only drug approved for dog treatment in Brazil. Further studies into drug susceptibility of L. amazonensis strains are warranted, especially in areas where dog infection by this species overlaps with those caused by Leishmania infantum.

Abstract
Leishmania major is the causative agent of cutaneous leishmaniasis (CL). It is one of the most studied Leishmania species not only during vector interaction, but also in the vertebrate host. Lipophosphoglycan (LPG) is the Leishmania multifunctional virulence factor during host-parasite interaction, whose polymorphisms are involved in the immunopathology of leishmaniasis. Although natural hybrids occur in nature, hybridization of L. major strains in the laboratory was successfully demonstrated. However, LPG expression in the hybrids remains unknown. LPGs from parental (Friedlin-Fn and Seidman-Sd) and hybrids (FnSd3, FnSd4A, FnSd4B and FnSd6F) were extracted, purified and their repeat units analyzed by immunoblotting and fluorophore-assisted carbohydrate electrophoresis (FACE). Parental strains have distinct profiles in LPG expression, and a mixed profile was observed for all hybrids. Variable levels of NO production by macrophages were detected after LPG exposure (parental and hybrids) and were strain specific. This article is protected by copyright. All rights reserved.

Comparative genomics of Leishmania isolates from Brazil confirms the presence of Leishmania major in the Americas. Int J Parasitol 2021; 51:1047-1057.

Abstract
Leishmania (Leishmania) major is an important agent of cutaneous leishmaniasis, having as a vector sandflies belonging to the genus Phlebotomus. Although this species has been described as restricted to the Old World, parasites similar to L. major have been isolated from South American patients who have never travelled abroad. These parasites were named "L. major-like", and several studies have been carried out to characterise them biochemically, molecularly, and biologically. However, the phylogenetic origin of these isolates is still unknown. In the present study we characterised three L. major-like isolates, named BH49, BH121 and BH129, using comparative genomics approaches. We evaluated the presence of gene and segmental duplications/deletions and the presence of aneuploidies that could explain the differences in infectivity observed in the BH49 and BH121 isolates. All isolates presented a pattern of mosaic aneuploidy and gene copy number variation, which are common in the genus Leishmania. Virulence factors such as phosphatases and peptidases were found to have increased gene copy numbers in the infective isolate, which could explain the difference in infectivity previously observed between BH121 and BH49. Phylogenetic analyses revealed that BH49, BH121 and BH129 L. major-like grouped with L. major isolates, and suggest they were imported from the Old World in at least two independent events. We suggest that new epidemiological inquiries should also evaluate L. major infections in South America, to assess the epidemiological importance of this species in the New World.

A follow-up study (2007-2018) on American Tegumentary Leishmaniasis in the municipality of Caratinga, Minas Gerais State, Brazil: Spatial analyses and sand fly collection. PLoS Negl Trop Dis 2021; 15:e0009429. [PMID: 34003866 PMCID: PMC8162678 DOI: 10.1371/journal.pntd.0009429] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Revised: 05/28/2021] [Accepted: 04/30/2021] [Indexed: 11/17/2022] Open
Abstract
Background The municipality of Caratinga is an important endemic area for American Tegumentary Leishmaniasis (ATL) and no epidemiological studies were performed during the past two decades. Here, we analyzed the epidemiological situation and the geographical distribution of ATL cases in the municipality of Caratinga from 2007 to 2018 using geographic information systems (GIS). Also, we evaluated the impact of several demographic parameters in ATL distribution and the sand flies incriminated in its transmission. Methods All demographic information (gender, age, educational level, clinical form, diagnostic criteria and case evolution) used in this study was retrieved from the public health archives and confirmed in the State Health Services databases. All cases were analyzed using GIS software based on ATL distribution. Also, non-systematic sand fly collections and molecular detection of Leishmania were performed in the hotspots. Results and conclusions During the period, ATL cases continued and increased especially in the past years (2016–2018). Hotspots included urban Caratinga areas and the districts of Patrocínio de Caratinga and Sapucaia. The species Nyssomyia whitmani, Nyssomyia intermedia, Migonemyia migonei and Evandromyia cortelezzii complex were captured. However, ITS1-PCR did not detect Leishmania DNA in those insects. Based on our analyses, urbanization of ATL in Caratinga has occurred in the past years. Due to the increase in the number of cases and vectors presence, it is recommended that health authorities focus on control measures in the most affected areas (Patrocínio of Caratinga and Sapucaia districts and urban Caratinga). Leishmaniasis is an important health problem in Latin American countries and worldwide. In some places, notification is limited and underreported hindering correct assessment of existing data. In Brazil, ATL is mainly caused by Leishmania (Viannia) braziliensis. It is transmitted by sand fly vectors Nyssomyia whitmani and Nyssomyia intermedia. ATL comprises different clinical manifestations including cutaneous leishmaniasis, muco-cutaneous leishmaniasis and atypical leishmaniasis. The objective is to present the spatial distribution of cases of ATL notified by the Public Health System of Caratinga between the period of 2007 and 2018. This city is one of the most important endemic areas in the State of Minas Gerais and compose the panel of knowledge on epidemiological aspects of cutaneous leishmaniasis caused by L. braziliensis. This information will be important for developing strategies for ATL control in the affected areas. There is strong evidence that supports ATL urbanization in the city of Caratinga and increase of cases in two rural districts (Sapucaia and Patrocínio de Caratinga).
