Abstract
Brain-derived neurotrophic factor (BDNF) is a neurotrophin of marked commercial, scientific, diagnostic, and therapeutic interest. The preservation of its structural cystine-knot is the main challenge in its industrial production. A suitable expression system is critical to achieve the most efficient production of bioactive and stable BDNF for pharmaceutical purposes.

Abstract
Currently, there are no evidence-based treatment options for long COVID-19, and it is known that SARS-CoV-2 can persist in part of the infected patients, especially those with immunosuppression. Since there is a robust secretion of SARS-CoV-2-specific highly-neutralizing IgA antibodies in breast milk, and because this immunoglobulin plays an essential role against respiratory virus infection in mucosa cells, being, in addition, more potent in neutralizing SARS-CoV-2 than IgG, here we report the clinical course of an NFκB-deficient patient chronically infected with the SARS-CoV-2 Gamma variant, who, after a non-full effective treatment with plasma infusion, received breast milk from a vaccinated mother by oral route as treatment for COVID-19. After such treatment, the symptoms improved, and the patient was systematically tested negative for SARS-CoV-2. Thus, we hypothesize that IgA and IgG secreted antibodies present in breast milk could be useful to treat persistent SARS-CoV-2 infection in immunodeficient patients.

Abstract
Monoclonal antibodies have contributed to improving the treatment of several diseases. However, limitations related to pharmacokinetic parameters and production costs have instigated the search for alternative products. Camelids produce functional immunoglobulins G devoid of light chains and CH1 domains, in which the antigenic recognition site is formed by a single domain called VHH or nanobody. VHHs' small size and similarity to the human VH domain contribute to high tissue penetration and low immunogenicity. In addition, VHHs provide superior antigen recognition compared to human antibodies, better solubility and stability. Due to these characteristics and the possibility of obtaining gene-encoding VHHs, applications of this biological tool, whether as a monomer or in related recombinant constructs, have been reported. To ensure antibody efficacy and cost-effectiveness, strategies for their expression, either using prokaryotic or eukaryotic systems, have been utilized. Plant-based expression systems are useful for VHH related constructs that require post-translational modifications. This system has exhibited versatility, low-cost upstream production, and safety. This article presents the main advances associated to the heterologous expression of VHHs in plant systems. Besides, we show insights related to the use of VHHs as a strategy for plant pathogen control and a tool for genomic manipulation in plant systems.

Abstract
Microorganisms living in the midgut of Anopheles mosquitoes have been studied to fight vector-borne diseases, such as malaria. Studies on the microbiota of the Neotropical Anopheles darlingi, the most important Brazilian vector for malaria, have been reported for the same purpose. Our aims were to isolate and identify culturable bacteria from An. darlingi mosquito guts through their feces and to estimate the species richness and the frequency distribution of the sampled bacteria. Sixty wild females of An. darlingi mosquitoes were captured at two rural locations, near Porto Velho, Rondônia, Brazil. Bacteria were isolated from mosquito feces, which were collected using cages which permit the collection of feces on LB nutrient agar plates. Sixty bacterial colonies were isolated and stored in glycerol at -80°C. Bacteria were identified by sequencing their 16S rRNA gene obtained using PCR and Sanger sequencing. To aid in species identification, MALDI-TOF, VITEK2, and BBL Crystal were used as complementary protocols. The sequences obtained from the 60 bacterial isolates were compared to sequences deposited in GenBank (NCBI) using BLAST. Homology greater than 97% between the query and the subject was used as the criteria for assigning the identity of each isolate. Fourteen species from eight different genera were identified among the 60 isolates. The most frequent species were Serratia liquefaciens (20%) and Serratia marcescens (15%). Due to their established apathogenicity and according to previous studies, we suggest Serratia and Pantoea species as suitable for paratransgenesis development to fight malaria in Brazilian Amazon.

Abstract
Given the magnitude of the global snakebite crisis, strategies to ensure the quality of antivenom, as well as the availability and sustainability of its supply are under development by several research groups. Recombinant DNA technology has allowed the engineering of monoclonal antibodies and recombinant fragments as alternatives to conventional antivenoms. Besides having higher therapeutic efficacy, with broad neutralization capacity against local and systemic toxicity, novel antivenoms need to be safe and cost-effective. Due to the biological and physical chemical properties of camelid single-domain antibodies, with high volume of distribution to distal tissue, their modular format, and their versatility, their biotechnological application has grown considerably in recent decades. This article presents the most up-to-date developments concerning camelid single-domain-based antibodies against major toxins from snake venoms, the main venomous animals responsible for reported envenoming cases and related human deaths. A brief discussion on the composition, challenges, and perspectives of antivenoms is presented, as well as the road ahead for next-generation antivenoms based on single-domain antibodies.

Abstract
BACKGROUND The surface of infected red blood cells (iRBCs) has been widely investigated
because of the molecular complexity and pathogenesis mechanisms involved.
Asymptomatic individuals are important in the field because they can
perpetuate transmission as natural reservoirs and present a challenge for
diagnosing malaria because of their low levels of circulating parasites.
Recent studies of iRBC antibody recognition have shown that responses are
quantitatively similar in symptomatic and asymptomatic infections, but no
studies have characterised the plasmodial proteins targeted by this
response. OBJECTIVES Our main objective was to identify Plasmodium falciparum
proteins associated with iRBC ghosts recognised by antibodies in the sera of
symptomatic and asymptomatic individuals in the Brazilian Amazon. METHODS We collected symptomatic and asymptomatic sera from patients residing in the
Brazilian Amazon and P. falciparum iRBC ghosts to identify
the proteins involved in natural antibody recognition by 2D-electrophoresis,
western blotting, and high- resolution mass spectrometry. FINDINGS 2D gel-based immunoproteome analysis using symptomatic and asymptomatic sera
identified 11 proteins with at least one unique peptide, such as chaperones
HSP70-1 and HSP70-x, which likely are components of the secretion
machinery/PTEX translocon. PfEMP1 is involved in antigenic variation in
symptomatic infections and we found putative membrane proteins whose
functions are unknown. MAIN FINDINGS Our results suggest a potential role of old and new proteins, such as
antigenic variation proteins, iRBC remodelling, and membrane proteins, with
no assigned functions related to the immune response against P.
falciparum, providing insights into the pathogenesis,
erythrocyte remodelling, and secretion machinery important for alternative
diagnosis and/or malaria therapy.

Abstract
Due mainly to properties such as high affinity and antigen specificity, antibodies have become important tools for biomedical research, diagnosis, and treatment of several human diseases. When the objective is to administer them for therapy, strategies are used to reduce the heterologous protein immunogenicity and to improve pharmacokinetic and pharmacodynamic characteristics. Size minimization contributes to ameliorate these characteristics, while preserving the antigen-antibody interaction site. Since the discovery that camelids produce functional antibodies devoid of light chains, studies have proposed the use of single domains for biosensors, monitoring and treatment of tumors, therapies for inflammatory and neurodegenerative diseases, drug delivery, or passive immunotherapy. Despite an expected increase in antibody and related products in the pharmaceutical market over the next years, few research initiatives are related to the development of alternatives for helping to manage neglected tropical diseases (NTDs). In this review, we summarize developments of camelid single-domain antibodies (VHH) in the field of NTDs. Particular attention is given to VHH-derived products, i.e., VHHs fused to nanoparticles, constructed for the development of rapid diagnostic kits; fused to oligomeric matrix proteins for viral neutralization; and conjugated with proteins for the treatment of human parasites. Moreover, paratransgenesis technology using VHHs is an interesting approach to control parasite development in vectors. With enormous biotechnological versatility, facility and low cost for heterologous production, and greater ability to recognize different epitopes, VHHs have appeared as an opportunity to overcome challenges related to the prevention, detection, and control of human diseases, especially NTDs.

Abstract
Antivenoms, produced using animal hyperimmune plasma, remains the standard therapy for snakebites. Although effective against systemic damages, conventional antivenoms have limited efficacy against local tissue damage. Additionally, the hypersensitivity reactions, often elicited by antivenoms, the high costs for animal maintenance, the difficulty of producing homogeneous lots, and the instability of biological products instigate the search for innovative products for antivenom therapy. In this study, camelid antibody fragments (VHH) with specificity to Bothropstoxin I and II (BthTX-I and BthTX-II), two myotoxic phospholipases from Bothrops jararacussu venom, were selected from an immune VHH phage display library. After biopanning, 28 and 6 clones recognized BthTX-I and BthTX-II by ELISA, respectively. Complementarity determining regions (CDRs) and immunoglobulin frameworks (FRs) of 13 VHH-deduced amino acid sequences were identified, as well as the camelid hallmark amino acid substitutions in FR2. Three VHH clones (KF498607, KF498608, and KC329718) were capable of recognizing BthTX-I by Western blot and showed affinity constants in the nanomolar range against both toxins. VHHs inhibited the BthTX-II phospholipase A2 activity, and when tested for cross-reactivity, presented specificity to the Bothrops genus in ELISA. Furthermore, two clones (KC329718 and KF498607) neutralized the myotoxic effects induced by B. jararacussu venom, BthTX-I, BthTX-II, and by a myotoxin from Bothrops brazili venom (MTX-I) in mice. Molecular docking revealed that VHH CDRs are expected to bind the C-terminal of both toxins, essential for myotoxic activity, and to epitopes in the BthTX-II enzymatic cleft. Identified VHHs could be a biotechnological tool to improve the treatment for snake envenomation, an important and neglected world public health problem.

Abstract
Snakebites are a frequently neglected public health issue in tropical and subtropical countries. According to the World Health Organization, 5 million people are bitten annually including up to 2.5 million envenomations. Treatment with antivenom serum remains the only specific therapy for snakebite envenomation. However, it is heterologous and therefore liable to cause adverse reactions, such as early anaphylactic, pyrogenic and delayed reactions. In order to develop alternatives to the current therapy, researchers have been looking for natural products and plant extracts with antimyotoxic, anti-hemorrhagic and anti-inflammatory properties. Especially due to the role the physiopathological processes triggered by snake toxins, play in paralysis, bleeding disorders, kidney failure and tissue damage. Considering the fact that studies involving snake toxins and specific inhibitors, particularly on a molecular level, are the main key to understand neutralization mechanisms and to propose models or prototypes for an alternative therapy, this article presents efforts made by the scientific community in order to produce validated data regarding 87 compounds and plant extracts obtained from 79 species. These plants, which belong to 63 genera and 40 families, have been used by traditional medicine as alternatives or complements to the current serum therapy.

Abstract
In addition to conventional antibodies, camelids produce immunoglobulins G composed exclusively of heavy chains in which the antigen binding site is formed only by single domains called VHH. Their particular characteristics make VHHs interesting tools for drug-delivery, passive immunotherapy and high-throughput diagnosis. Hantaviruses are rodent-borne viruses of the Bunyaviridae family. Two clinical forms of the infection are known. Hemorrhagic Fever with Renal Syndrome (HFRS) is present in the Old World, while Hantavirus Pulmonary Syndrome (HPS) is found on the American continent. There is no specific treatment for HPS and its diagnosis is carried out by molecular or serological techniques, using mainly monoclonal antibodies or hantavirus nucleoprotein (N) to detect IgM and IgG in patient serum. This study proposes the use of camelid VHHs to develop alternative methods for diagnosing and confirming HPS. Phage display technology was employed to obtain VHHs. After immunizing one Lama glama against the recombinant N protein (prNΔ85) of a Brazilian hantavirus strain, VHH regions were isolated to construct an immune library. VHHs were displayed fused to the M13KO7 phage coat protein III and the selection steps were performed on immobilized prNΔ85. After selection, eighty clones recognized specifically the N protein. These were sequenced, grouped based mainly on the CDRs, and five clones were analyzed by western blot (WB), surface plasmon resonance (SPR) device, and ELISA. Besides the ability to recognize prNΔ85 by WB, all selected clones showed affinity constants in the nanomolar range. Additionaly, the clone KC329705 is able to detect prNΔ85 in solution, as well as the native viral antigen. Findings support the hypothesis that selected VHHs could be a powerful tool in the development of rapid and accurate HPS diagnostic assays, which are essential to provide supportive care to patients and reduce the high mortality rate associated with hantavirus infections.

Abstract
Phospholipases A2 (PLA2s) from snake venoms comprise a group of 14-18 kDa proteins, responsible for several toxic effects induced by the whole venom. Considering this, studies aiming at the search for natural inhibitors of these proteins are very important. The present work had as objectives the isolation and functional/structural characterization of a γ-type phospholipase A2 inhibitor (PLI) from Bothrops jararacussu snake plasma, named γBjussuMIP. This acidic glycoprotein was isolated in a high purity level through affinity chromatography on CNBr-Sepharose 4B coupled with BthTXII, showing a pI ∼ 5.5 and molecular weight of 23,500 for the monomer (determined by SDS-PAGE), and 160,000 for the oligomer (determined by molecular exclusion chromatography on Sephacryl S-200). The interaction between γBjussuMIP (MIP) and Phospholipase A2 (PLA2) was confirmed using circular dichroism (CD) and emission fluorescence techniques. The helical content of the 1:1 molar mixture was higher than that calculated for the addition of the spectra of the unbound proteins indicating binding. The emission fluorescence experiments pointed that Trp residues in PLA2 participate in proteins interaction as blue shift of 4 nm was observed. The γBjussuMIP cDNA, obtained by PCR of the liver of B. jararacussu snake, revealed 543 bp codifying for a mature protein of 181 amino acid residues. Alignment of its amino acid sequence with those of other snake γPLIs showed 89-94% of similarity. γBjussuMIP mainly inhibited the pharmacological properties of Asp49 PLA2s, such as phospholipase, anticoagulant, myotoxic, edema inducing, cytotoxic, bactericidal and lethal activities. In addition, it showed to be able to supplement Bothrops antivenom, potentiating its antimyotoxic effect. The aspects broached in this work will be able to provide complementary information on possible mechanisms of action, relating structure and function, which could result in a better understanding of the inhibitory effects induced by γBjussuMIP.

Abstract
Proteoliposomes are systems that mimic lipid membranes (liposomes) to which a protein has been incorporated or inserted. During the last decade, these systems have gained prominence as tools for biophysical studies on lipid-protein interactions as well as for their biotechnological applications. Proteoliposomes have a major advantage when compared with natural membrane systems, since they can be obtained with a smaller number of lipidic (and protein) components, facilitating the design and interpretation of certain experiments. However, they have the disadvantage of requiring methodological standardization for incorporation of each specific protein, and the need to verify that the reconstitution procedure has yielded the correct orientation of the protein in the proteoliposome system with recovery of its functional activity. In this review, we chose two proteins under study in our laboratory to exemplify the steps necessary for the standardization of the reconstitution of membrane proteins in liposome systems: (1) alkaline phosphatase, a protein with a glycosylphosphatidylinositol anchor, and (2) Na,K-ATPase, an integral membrane protein. In these examples, we focus on the production of the specific proteoliposomes, as well as on their biochemical and biophysical characterization, with emphasis on studies of lipid-protein interactions. We conclude the chapter by highlighting current prospects of this technology for biotechnological applications, including the construction of nanosensors and of a multi-protein nanovesicular biomimetic to study the processes of initiation of skeletal mineralization.

Abstract
This article addresses the interactions of the synthetic antimicrobial peptide dermaseptin 01 (GLWSTIKQKGKEAAIAAA- KAAGQAALGAL-NH(2) , DS 01) with phospholipid (PL) monolayers comprising (i) a lipid-rich extract of Leishmania amazonensis (LRE-La), (ii) zwitterionic PL (dipalmitoylphosphatidylcholine, DPPC), and (iii) negatively charged PL (dipalmitoylphosphatidylglycerol, DPPG). The degree of interaction of DS 01 with the different biomembrane models was quantified from equilibrium and dynamic liquid-air interface parameters. At low peptide concentrations, interactions between DS 01 and zwitterionic PL, as well as with the LRE-La monolayers were very weak, whereas with negatively charged PLs the interactions were stronger. For peptide concentrations above 1 µg/ml, a considerable expansion of negatively charged monolayers occurred. In the case of DPPC, it was possible to return to the original lipid area in the condensed phase, suggesting that the peptide was expelled from the monolayer. However, in the case of DPPG, the average area per lipid molecule in the presence of DS 01 was higher than pure PLs even at high surface pressures, suggesting that at least part of DS 01 remained incorporated in the monolayer. For the LRE-La monolayers, DS 01 also remained in the monolayer. This is the first report on the antiparasitic activity of AMPs using Langmuir monolayers of a natural lipid extract from L. amazonensis.

Abstract
Snake Venom L-amino acid oxidases (LAAOs E.C. 1.4.3.2) are flavoenzymes broadly found in various snake venom compositions. LAAOs have become an attractive subject for molecular biology, biochemistry, physiology and medicine due to their actions on various cells and biological effects on platelets, apoptosis, hemorrhage and others. In this review we try to summarize some of these reports, with special emphasis on apoptosis, anti-protozoa, bactericidal and anti-viral activities.

Abstract
Lipid microspheres (LM) are excellent drug delivery or vaccines adjuvant systems and are relatively stable. The aim of this work is to develop and characterize a system that is able to encapsulate and present antigenic membrane proteins from Leishmania amazonensis. Membrane proteins are important for vaccine's formulation because these proteins come in contact with the host cell first, triggering the cell mediated immune response. This is a useful tool to avoid or inactivate the parasite invasion. The LM are constituted by soybean oil (SO), dipalmitoylphosphatidilcholine (DPPC), cholesterol and solubilized protein extract (SPE). The particles formed presented an average diameter of 200 nm, low polydispersion and good stability for a period of 30 days, according to dynamic light scattering assays. Isopycnic density gradient centrifugation of LM-protein showed that proteins and lipids floated in the sucrose gradient (5-50%w/v) suggesting that the LM-protein preparation was homogeneous and that the proteins are interacting with the system. The results show that 85% of SPE proteins were encapsulated in the LM. Studies of cellular viability of murine peritoneal macrophages show that our system does not present cytotoxic effect for the macrophages and still stimulates their NO production (which makes its application as a vaccine adjuvant possible). LM-protein loaded with antigenic membrane proteins from L. amazonensis seems to be a promising vaccine system for immunization against leishmaniasis.

Abstract
Phospholipases A2 (PLA2s) are commonly found in snake venoms from Viperidae, Hydrophidae and Elaphidae families and have been extensively studied due to their pharmacological and physiopathological effects in living organisms. This article reports a review on natural and artificial inhibitors of enzymatic, toxic and pharmacological effects induced by snake venom PLA2s. These inhibitors act on PLA2s through different mechanisms, most of them still not completely understood, including binding to specific domains, denaturation, modification of specific amino acid residues and others. Several substances have been evaluated regarding their effects against snake venoms and isolated toxins, including plant extracts and compounds from marine animals, mammals and snakes serum plasma, in addition to poly or monoclonal antibodies and several synthetic molecules. Research involving these inhibitors may be useful to understand the mechanism of action of PLA2s and their role in envenomations caused by snake bite. Furthermore, the biotechnological potential of PLA2 inhibitors may provide therapeutic molecular models with antiophidian activity to supplement the conventional serum therapy against these multifunctional enzymes.

Abstract
A thrombin-like enzyme named BjussuSP-I, isolated from B. jararacussu snake venom, is an acidic single chain glycoprotein with approximately 6% sugar, Mr=61,000 under reducing conditions and pI approximately 3.8, representing 1.09% of the chromatographic A(280) recovery. BjussuSP-I is a glycosylated serine protease containing both N-linked carbohydrates and sialic acid in its structure. BjussuSP-I showed a high clotting activity upon human plasma, which was inhibited by PMSF, leupeptin, heparin and 1,10-phenantroline. This enzyme showed high stability regarding coagulant activity when analyzed at different temperatures (-70 to 37 degrees C), pHs (4.5 to 8.0), and presence of two divalent metal ions (Ca(2+) and Mg(2+)). It also displayed TAME esterase and proteolytic activities toward natural (fibrinogen and fibrin) and synthetic (BAPNA) substrates, respectively, being also inhibited by PMSF and leupeptin. BjussuSP-I can induce production of polyclonal antibodies able to inhibit its clotting activity, but unable to inhibit its proteolytic activity on fibrinogen. The enzyme also showed crossed immunoreactivity against 11 venom samples of Bothrops, 1 of Crotalus, and 1 of Calloselasma snakes, in addition of LAAO isolated from B. moojeni venom. It displayed neither hemorrhagic, myotoxic, edema-inducing profiles nor proteolytic activity on casein. BjussuSP-I showed an N-terminal sequence (VLGGDECDINEHPFLA FLYS) similar to other thrombin-like enzymes from snake venoms. Based on its biochemical, enzymatic and pharmacological characteristics, BjussuSP-I was identified as a new thrombin-like enzyme isoform from Bothrops jararacussu snake venom.
